More Info:
Lookup table should include a DeletionDate column.

There could be an instance where the same code will have a deletion date
then be reintroduced. I would need to account for that as well.

Win XP
Excel '03

I have two tables, one is my data table and the other is a lookup table. In
the lookup table I keep track of Introduction and Discontinuation dates. The
Data table is updated monthly with the monthly date stored. I could have
code 301 in January-05 and it will be 'active' but by March-05 it has been
discontinued. I would like my report to place the amount measured in the
appropriate category in the appropriate month.

LOOKUP:
Col A Code
Col B Intro Date
Col C Status

DATA:
Col A Code
Col B Month
Col C Status
Col D Amount

I hope this makes sense. Let me know if it doesn't.

Thanks in advance,
Tanya
