A family of Microsoft spreadsheet software with tools for analyzing, charting, and communicating data.
Normally you would write something like IF(my_expression<0,0,my_expression) but having to repeat the expression is both inefficient and error prone. The LET function address this concern.
=LET(x,ABS(SUMIFS($E2:$L2,$A2:$H2,"COFIELD")+0),IF(x<0,0,x)
I don't know what the +0 at the end of ABS accomplishes.
