Tag a Record in a List when comparing to another list.
I have a list of e-mail addresses that is about 10,000 e-mail adresses. (We can call this the Main List)
I will be getting short lists of e-mail addresses that another part of the company e-mailed something to. (We can call this the Short List)
I will then want to tag each of the records in the Main List that the person was mailed to a specific named mailing. If the persons e-mail in teh Short List, was not allready on the Main List, then I will want to add his e-mail address to the Main List at that time.
What is the simplest way for an advanced beginner of FMP to do this?
