I have in one file the Account Name and Part Number.

Substitute ( Match CM Name & Match Part ; " " ; "" )

In the other file I have a calculation from 2 tables, because in that file the Account Name is in a different table than the part.

Substitute ( DIT:: CM Name & MatchPart; " " ; "" )

So, the basics are that I need to match both the CM Name AND the Part Number, and all it has to do is flag the line item from the first file if there is a match on the criteria in the 2nd file.

I've gone over and over this, and I can get the lookup to work if it's just on one criteria - like one DB to one table in the other, but when I try to do it with these calcs, it fails. As a side note, I did have this same calculation set up in the old file (which I'm trying to get rid of by doing this), and it always worked there where there was only 1 table.

So, I'm thinking it's because my calc in the 2nd fle takes info from 2 tables.

Any advice would be great!

Thank you.

Figured it out. The 2nd file is not indexing

I never saw this post, sorry. You've found out that you can't index a field that involves a global or related field. So it can only be used as the left-hand key of a relationship, not the right-hand one.
