I have created a simple letter and use Excel as the data source. When I merge the document on my PC at home it creates the correct number of letters to correspond with the number of records However, when I use the exact same templates on the computer in work, it creates an additional 30 or so blank letters! I have tried deleting columns and rows in case there is a rogue character somewhere but it still does this. Any ideas why?

Are the versions the same? Have you tried just entering the data in a real database (Access) and creating your letters that way? Life's more painless for the brainless.

When you say "blank letters" do you mean templates with your text but without addresses or blank sheets, period? If they are blank, are they mixed in with the "real" letters or all at the end? I ask because I'm wondering if the Print Set-up is different because of a different printer and causing each letter to create a blank page due to a larger margin puching a line feed or two to another page. I see that in docs I receive at work. If that's not it... I'm not sure if this will help, but it might tell us something: When you get to the step where you can edit the recipient list, click the link and see if there are more items in the list than your actual list, such as blank lines with check marks.
