Search for subform record based on text box

I am trying to bring up a form record based on text entered in a text box.

The form "Furnace + Header Data Form" is a parent form, with 2 subforms called "Header Data Form" and "Surrogate Data Form". This question is in relation to the "Header Data Form" subform.
The parent form is used to enter data on different furnace runs, which is connected to the table "Furnace Run Data". Each furnace run will have several headers in it, and each header has a serial number. I added a subform called "Header Data Form", which will allow the user to enter information specific to each header serial number. Data that is entered into the "Header Data Form" subform adds data to the "Header Data" table and is connected to the furnace data table via the Furnace Run ID. The Furnace Run ID is on both the parent form and as an invisible field on the Header Data subform. All fields on the Header Data Form are connected to the Header Data Table.

As a side note, there is a button within this subform to add a new record. Once the button is clicked, a new record with the furnace data and header data is saved and the header data subform is cleared. When you enter more data into the header data form and click the add button, another line (with the same Furnace Run ID) will be added to the header data table. No data is added to the furnace table. This all works great. There are multiple records in the Header Data table for each Furnace Run ID.

Initially, I was trying to find the record based on a text field named "Header SN Field" on the subform named "Header Data Form". This text field is connected to the "Header SN" Field from the "Header Data" table. Upon clicking the search button (on the Header Data subform), I wanted to use the text typed into the Header SN Field to search for the previous record in the Header Data table that has Header SN (field in Header Data table) = Header SN Field (field in form where user enters text). I could get this to run with no errors, but I kept getting the message saying that no matching record was found, even though there definitely is an existing record with the matching Header SN. My code for this is below.

Private Sub Search_SN_Button_Click()
If ([Header SN Placeholder] & vbNullString) = vbNullString Then Exit Sub
Dim strCriteria As String
Dim rs As DAO.Recordset 

Set rs = Me.RecordsetClone  
  
strCriteria = "[Header SN]='" & Me.[Header SN Field] & "'"  
  
rs.FindFirst strCriteria  
  
If rs.NoMatch Then  
    MsgBox "Sorry, no such record '" & [Header SN Field] & "' was found.", _  
           vbOKOnly + vbInformation  
Else  
    Me.Bookmark = rs.Bookmark  
End If  
rs.Close  
txtGoTo = Null

End Sub

After searching a bit, I thought the solution might be to have a text box and search button on the main form instead. The text box on the main form is called "HeaderSN". I am still getting the message that there is no existing record that matches. My code for this is below.
Private Sub Search_Header_SN_Record_Click()
If (HeaderSN & vbNullString) = vbNullString Then Exit Sub
Dim strCriteria As String
Dim rs As DAO.Recordset 

Set rs = Me.[Header Data Form].Form.RecordsetClone  
  
strCriteria = "Header SN = '" & Me.HeaderSN & "'"  
  
rs.FindFirst strCriteria  
  
If rs.NoMatch Then  
    MsgBox "Sorry, no such record '" & [HeaderSN] & "' was found.", _  
           vbOKOnly + vbInformation  
Else  
    Me.[Header Data Form].Form.Bookmark = rs.Bookmark  
End If  
rs.Close  
txtGoTo = Null

End Sub

Can someone please help me with this? I have tried a million different ways to do this and have been searching for days on different forums but I can't figure it out.

    @Ken Sheridan Unfortunately I can't share things outside of my organization on sites like OneDrive or Google Drive without an email/name to send it to

    All I can suggest is that you post your file, stripped of any personal or otherwise sensitive data, to a site such as Microsoft's OneDrive, and post the link in a reply here so that we can take a look at it.

    @Ken Sheridan Thank you for all the help. I have been playing around with this all morning and still can't figure it out. I have tried using this with the button and search field on the main form and subform, and have tried it with the first part of your first example + the second part or + the current event procedure. Please let me know if you think of anything else I can try.

    The only obvious problem I can see with your latest code is that there is inconstancy with regard to the data type of the Header SN column. In the command button's Click event procedure it is treated as a text data type and wrapped in single quote characters. In the subform's Current event procedure it is treated as a number data type and not delimited with quote characters:

    .RecordsetClone.FindFirst "[Header SN] = " & Me.[Header SN Placeholder]

    As you are already filtering the subform, however, the code in the Current event procedure is not necessary and can be deleted. In my demo the code in the Current event procedure is used in the example where the subform is not filtered.

    @Ken Sheridan

    I have even tried to separate them as you did, and I still don't get anything in the subform fields. 

        Private Sub Search_SN_Button_Click()  
        Const MESSAGETEXT = "No matching records found."  
         Dim ctrl As Control  
         Dim strFilter As String  
         Dim rs As DAO.Recordset  
              
         Set ctrl = Me.[Header SN Placeholder]  
            'Header SN Placeholder is not bound to the table, formula equals text entered in Header SN Field textbox on subform  
         strFilter = "[Furnace Run ID] IN(SELECT [Furnace Run ID] " & _  
             "FROM [Header Data] WHERE [Header SN] = """ & ctrl & """)"  
              
         If Nz(ctrl, 0) = 0 Then  
             ' turn off filter  
             Me.Parent.FilterOn = False  
             Me.Parent.[Header Data Form].Form.FilterOn = False  
         Else  
             If Not IsNull(DLookup("[Header SN]", "[Header Data]", "[Header SN] = '" & ctrl & "'")) Then  
                 ' filter form to name selected in text box  
                 Me.Parent.Filter = strFilter  
                 Me.Parent.FilterOn = True  
                   
                 ' filter subform to selected Header SN  
                   Me.[Parent].[Header Data Form].[Form].Filter = "[Header SN] = '" & ctrl & "'"  
                   Me.[Parent].[Header Data Form].[Form].FilterOn = True  
                   Else  
                 ' inform user if no matching records found  
                 MsgBox "Sorry, no such record '" & [Header SN Placeholder] & "' was found.", _  
                 vbOKOnly + vbInformation  
               
            End If  
        End If  
End Sub

    With the on current as: 

        Private Sub Form_Current()  
     If Not IsNull(Me.[Header SN Placeholder]) Then  
         With Me.Form  
             .RecordsetClone.FindFirst "[Header SN] = " & Me.[Header SN Placeholder]  
             If Not .RecordsetClone.NoMatch Then  
                 .Bookmark = .RecordsetClone.Bookmark  
             End If  
         End With  
     End If  
    End Sub
