Wow, thank you so very much for all the responses. I've gone blind
looking at these amounts over the past few days so I really appreciate
the responses. First off, amongst some of my accountant co workers I
know alot about excel but the VBE stuff is a bit shady for me. I've
done some macros but the code Mr. Thomlinson provided is a bit out of
my league. I'd need a more thorough explanation as to how to set up
the code for me to make that work. I pasted it into VBE and turned on
those options but I don't know what to do thereafter. I also want to
try out the solver option but I need to have it installed. I'll have
to try it at work tomorrow morning, man I really didn't expect all
these responses this quickly, guess it helps posting in more than one
group.

For the record it seems that a few of the invoice amounts were missing
from my list hence the huge problem with matching them up to payments.
Even with that i still have some matching issues. I also forgot to
mention that an invoice amount once used when matched to a payment
cannot be used again. The combinations of course must match up to the
payments to the penny.

Again I really would like to try the VBE FindSum program but I'll need
some newbie introduction into how to write a code like that and then
how to use it. Thanks again!
