Deb:
It's hard to describe what to do without actually seeing the file. Your Adagio consultant would be able to help correct it.

But a quick and inexpensive solution is to restore the Invoice spec file from before you made changes. To determine the name, open the Invoice Designer and then click on the "Open" button. The selection box will show both the name you have given it and the actual filename beginning with "QI$". Restore that file and just that file. You must be careful when restoring to not restore the other files or you will have to redo your work. If you aren't 100% comfortable with restoring, you should not proceed.
