I have four Microsoft Excel workbooks (excel spreadsheets). One is a list of Donors and the other three are separate campaigns which had click-throughs from an email blast. What I've been asked to do is to find out which click-throughs actually donated to that campaign.
Hope this makes sense. I'd love some help on what to do...be it a macro or formula to tie together two workbooks, or perhaps there's a simpler solution I'm missing.
