Ok I managed to fix the Acer add in thing that was messing with GM's Many to One function. So now that that's working, I have everything perfectly set up cause I just run that after my "Delete rows with $ macro". Thanks for your help Paul!

BTW, just a side question: for some reason, now every time I open a Word document, it opens as though the document type were Email Message. I've tried reselecting the document type "Letters" and as "Normal Word Document" in the START MAIL MERGE menu, saving, resaving, renaming, etc. but nothing's working. Any word file I open, it goes straight into Email message document type. This is messing up Grahams Many to One function, as well as the layout of my letter.

Randomly, after a day or so, I'll come back and everything's back to Letter mode

I've been looking around but can't seem to find anything... I'm pretty desperate. Any ideas? Thanks!!
