Delete Fails on table with two form select fields

Delete Fails on table with two form select fields

I created a table with two form single select fields, and successfully imported the data from a paste of csv data (it came from an MS Access database).

However, while I could add records, I could not delete anything - after getting confirm delete popup just get an "error deleting record" pop-over without any further explanation.

So I tried another way. I saved my script definition, deleted the form, then created a new form (with same name), used edit script to put exactly the same script back. Then accessed the application and attempted to paste the data into it. Got no error report, but the display of the data has the "right" number of rows, but they all appear empty. Tried various view options (list, spreadsheet etc.,.), but still no data appears.

The application is http://creator.zoho.com/wombatk/lines-register/, and the troublesome form is the Sites one.

Am I doing something wrong, or is zoho incapable of handling more than one form select field per form ?
