Hello InstaDRY,
Oops, I didn't refresh the page in time. Here are my notes if anyone else encounters the problem.
It could be several things.
First, there may be a field that is outside of the report boundaries. Watch where you margins are on the page in relation to it's fields. Are any margin lines red?
Second, you could have a field that has a large value. This can increase the size of the field and expand it over the boundaries of the page.
I hope this helps,
Greg
