Excel - Expense tracking-multiple users

Have 7 ppl sending me bi-monthly expense updates via Excel. Then I have to
take all their "new" updated data and incorporate into a Master .xls, which
the 7 ppl can't access directly unfortunately. Problem is, when I get the
updates from the 7 ppl, I need to be able to see what is "new" data since
their previous update. I've been reading about History sheets in Track
Changes, but it's all getting a little confusing. Can some expert out there
help me think through a solution, because I'm sure there's one out there! I
need to write up a set of instructions for each of the 7 users, since they
will control their own data worksheets.

If their data is cumulative for the entire month simply overwrite the old
data with the new.
Otherwise a macro to check for duplicates
If desired, send your file to my address below. I will only look if:
1. You send a copy of this message on an inserted sheet
2. You give me the newsgroup and the subject line
3. You send a clear explanation of what you want
4. You send before/after examples and expected results.
