One way:

=SUM(IF((A1:A100=M1)*(A1:A100<=N1),B1:J100))

Array-entered, meaning press ctrl + shift + enter, where
M1 holds the start date and N1 holds the end date.

I have dates in column A and numbers in column B-J. I
need columns B-J to
add up if dates in A are within a range. For example:
if A is between
9/21/2004 and 9/20/2005, then add those lines in column
B.
