I've set up an InfoPath form and SP list. It was working fine and submitting to the list. However I set up some Form Load and Form Submit rules which threw up some errors. Then I noticed that the data wasn't appearing in the list. When I submit the form nothing happens. No errors, the form just closes and nothing appears in the list. I've disabled the rules, so theoretically I should be back to where I was, but I'm actually a step back. Any ideas why the data isn't appearing on the list?
A quick solution to this type of problem is to really step back, disable all rules and keep simple form submit to list. Test that and if that works then apply rules one by one and test until you come to a rule that cause the issue.
