I have an example with 2 columns in excel sheet:
X --- Y
1 --- A
2 --- A
3 ---
5 ---
1 --- A
Column Y was hidden by the formula: =IF(A2<=2,"A","")
I want to sum if column X if Y is not blank. I use this formula: =SUMIF(B:B,"<>",A:A) but it not understand that "" is blank.
I hope somebody can help me.
