I have read similar questions but unfortunately didn't help me.
Here is a copy (with sensitive info redacted) of my data.Google Sheet
In column U and V I am trying to sum columns D to O if T is "A" or "B" respectively. e.g. =sumif($T3,"A",$D3:$O3)
I have formatted all the numbers as automatic. I have formatted column T as plain text.
Only some of the formulas seem to work and I can't figure out why?
