I am trying to nest 12 if functions with no success, I have read several other posts regaring this and have tried some of the suggested formulas but still can't get it to work right, please help! :rolleyes:

Here is the formula:
=(IF($AF$74=1,B78,"")&IF($AF$74=2,SUM(B78:C78),"")&IF($AF$74=3,SUM(B78:D78),"")&IF($AF$74=4,SUM(B78:E78),"")&IF($AF$74=5,SUM(B78:F78),"")&IF($AF$74=6,SUM(B78:G78),"")&IF($AF$74=7,SUM(B78:H78),"")&IF($AF$74=8,SUM(B78:I78),"")&IF($AF$74=9,SUM(B78:J78),"")&IF($AF$74=10,SUM(B78:K78,"")))

So the idea is that if cell equals 1 then return a value, if cell equals 2 then sum 2 values and return, if cell equals 3 then sum 3 values and return. When I enter the formula above I get a #VALUE error. What am I doing wrong?

Thanks!!! :rolleyes: :rolleyes:

You are better off setting up a table with your data and creating a LOOKUP formula instead.

=SUM(OFFSET(B78,,,AF74))

Addendum

As Oaktree pointed out I had missed a comma - Grrrrrr - Serves me right for just typing it and not trying it. :oops:

=SUM(OFFSET(B78,,,,AF74))

Try = sum(B78:eek:ffset(B78,0,$af$74-1))

edit: I like Ken's more, but I think his should have 4 commas instead of 3

=SUM(OFFSET(B78,,,,AF74))

The reason it isn't working, is that the & operator makes it text not number, even though it looks like a number.
