Sorry Julie.

I had to remove your link to that webpage. It was a commercial product and NOT related to the question. You can reform the link below and see for yourself.

I forgot to answer my own question. It's really important. If someone ran into the same issue.

Here is how its done:

 Dim ss As String = Await WebView1.InvokeScriptAsync("eval", New String() {"document.getElementById('cX_l').value;"})

If you were to ensure the element was found

e.g. Dim functionString = String.Format("document.getElementsById('cX_l')[0].value;")

What is the variable ss returning ?
