variable formula

[LP23294]

how do i write a formula to do a variable sum calculation. ie i have a column
of numbers in A from A5 going down to A25. in cell F1 i have a value between
1 and 20. this example F1 = 7.
so the value in the formula would be A5+ the value in F1 (7) which would
equal A12.

so the final formual would be =sum(A5:A5+value in f1).
=sum(a5:a12)

Try

=SUM(OFFSET(A5,0,0,F1+1,1))

If this post helps click Yes

so the final formual would be =sum(A5:A5+value in f1).

=sum(a5:a12)

Try this:

=SUM(A5:INDEX(A5:A25,F1+1))

If F1 is empty the result will be the sum of A5:A5.
