Well, small steps...
I added the field to the table then went to duplicate the screen and add the field. Once duplicated, field added, saved then tested, an error message popped up.
I then removed the added field, saved it and tested it again... adding a new invoice, fails.
I then deleted the newly added "New/Edit Invoice" screen and attempted it again. That is, make a copy of the screen... NO new fields added. Then upon addin a new invoice, I get a screen that indicates:
The ActiveRecordChange event for New / Edit Invoice(2) failed to complete.
Message: Filter cannot be found
Stack Trace:#2 - Action Set (btnGridAppearance_onClick), #2 - Condition, #1 - SetViewFilter (If)
Please verify and try again. If the problem persists please contact Method Technical Support.
Stuck.
