These are the exact steps I take to achieve error message;

1. Open OE
2. Select "Maintenance"
3. Select "Maintain Specification" (Order Designer opens)
4. I select "Open" Then select the invoice i want to modify, in this case oe$inpck.***
5. I can select/delete/move any item but , when I select field/label etc... and try to put one of these fields in the form I get a pop up that says;
ADAGIO/INVOICE ORDER DESIGNER
X DIVISION BY ZERO
I cannot modify any form without getting this message.


Please advise.
