Excel公式：如果列B的值在X和Y之间，则添加列A的值

Question

I've been looking all over for an answer to this, but I've had a hard time finding one.

My data looks like this, but much longer:

Sessions (A)   Screen Width (B)
875            1020
869            1580
864            1520
809            1420

I'm looking for a formula that will come up with a sum of all values in column A, but only if the value in column B is between 768 and 1024 (as one example).

I am but a lowly designer, and do not understand things like numbers and formulas. :)

Seriously though, I tried SUMIF and SUMIFS and a few other things, but couldn't figure out if I was on the right path or not.

I really appreciate the help. Thanks!

Answer 1

Thanks to Scott Craner:

=SUMIFS(A:A,B:B,">=768",B:B,"<=1024")

I had a secondary problem, which was that my Column A values were stored as text rather than numbers, which why everything I tried kept coming up 0. To fix that, I had to include Value() in my formula.
