I have the require once line of code at the start of the page. When I create all the pages using Dataassist the insert page is the only one that populates this error. I have been using Dataassist for a long time now and never had this error before.
The connection file works fine for all the other pages (Update etc, but does not for the Insert page). I have ran the wizzard several times and even with no template and it still produces the error.
I have attached the inset page code if this helps
