Hi

I am using formula,

{=SUM(IF($B$66:$B$200=A28,$D$66:$D$200))}

But what if I don't know the coulmn number, i.e. 'D' In my source file
values which I want to retriev are not always in D column, it could b E or F
and evry time I don't want to update my formula...

Coloum Header is always same but not column number. Is ther any way to
retreive column number by using column header and then use that in above
array formula?

Please advise
