I have a form that includes a table. The table has a single line field and a dropdown field with row settings as shown below. There is no CSS or java associated with the table. Additionally, there are no lookups or field rules.
However, when I am in preview mode each time I attempt to enter information and click add to add an additional column, it causes the form to reset (returning to the first page of the form from page 3) and only offers the submit button (and no information is actually submitted).
There IS a lot going on in this form, so I am sure I have done something weird, but I cannot for the life of me imagine what could be interfering with simply adding a row to a table.
