I have created a custom-sized envelope for a mail merge and it works
beautifully except for one thing: after each envelope is a blank 8.5 x 11
page.

The merge envelope, when created, comes out with a "next page section break"
at the top. If I delete that, all the formatting gets deleted for the
envelope.

Please help! All I want to do is merge our data source with custom envelopes.

Any help would be appreciated.
