I have an IG on a form and it is based on a table. It has 3 fields, 2 are select lists and the third is a display only of a calculated date after the data from the select lists is 'saved'. The first select list is a SQL query to populate the list and the second is a 'shared component' of static values. The problem occurs whenever I make a selection from the 1st list and tab to the 2nd field. It worked in 5.1 (it was developed there) and has since broken when it was migrated to 18.2. I have looked at the other discussions for this error when the error was on a calculated or hidden field but they are no help since neither situation applies here. There are no calculations or validations on either select list, just displaying the values for the user to make the selection. This is a view of the form that throws the error:

This is a view of the error console after the error:

Any help greatly appreciated.
Thanks,
