I have the following SUMPRODUCT formula: =SUMPRODUCT(((A2:A11=X1)*(B1:K1<=X2))*B2:K11)
How would you re-formulate this formula to use it across different sheets? For instance, Sheet 1 to 4.
I am a little bit familliar with the INDIRECT fuction but I wasn't able to solve it so far.
Would appreciate any help.
Thank you.
