For some time I have been using mail merge to address a quantity of envelopes every month - this month I got a message on the screen saying I had to many data fields when I tried to select the data source! I was then told install address validation software. When I went to the Microsoft Office Web Site and typed in "Address validation software" I was told that this produced NIL results!!! Any help please urgently as I have to get 97 envelopes posted to-night!!!
