Hello Alteryx,
Needing your help to share to me your simpler formula on below. I have an input data that generated activity and ytd balances from January up to December.
I would like to multiply to -1 all yellow column with this condition: If GL Account type (in orange) is a Liability, Equity and Income, then column K - column AH (January - December) should be multiply by -1.

Attached is the dummy input file for your reference.
