Hello.

I am trying to add up cells that already have sum values in them. The
formula looks like this:

=B23 + B28

Unfortunately, when I add these two cells together, the value I am getting
is 0.
B23 and B28 are cells that have formulas that look like this:

B23
=SUM(B2:B22)
and
B28
=SUM(B25:B27)

I don't understand why adding these two cells together are resulting in a
value of zero
B23


HELP!!! I just upgraded to Office 2003, and this worked on my previous version
