Sum X Number of Columns
 

Hi and thanks in advance for any help provided. I am trying to simplify a
nested if statement formula that sums columns of data based on the number in
another column. Here is an example:

Weeks to Sum Wk1 Wk2 Wk3 Wk4 Wk5 Wk6 Wk7 Wk8
4 100 150 160 170 180 200
200 200
2 50 60 70 70 70 65
60 60
etc...

In the first line, I need to sume the first 4 values for a total of 580, in
the second line I need the sum of the first 2 for a total of 110. It seems
like there must be a simple formula to do this but my search has come up
empty.

Thx

I'm not clear on what you want. You want a total of the first 4 in the
first row (row 2?), first 2 in row 3? How many rows are you summing?

If the number of Weeks to Sum is in A1, and your data starts in B1, then:

=SUM(OFFSET(A1,0,1,1,A1))

--ron

Sum X Number of Columns
 

Here is one solution among many:

=SUM(OFFSET(B2,,,,A2))

Assume that the you enter the items (weeks data) starting in B2 and you
enter the number of columns you want to sum in A2. Then in a blank cell
enter the above formula.

One mo

=IF(A2=0,"",SUM(B2:INDEX(B2:H2,A2)))

Adjust the columns to match.

Thanks all! The OFFSET function is exactly what I was looking for.
