What does the "Submit" button do?
Exit Silly question mode ...
In IWP, when you enter a record, the toolbar gives you two options Submit and Cancel. If you Submit then the changes are commited and sent to the server. In regular FM, whenever you click out of a field it commits the data automatically but in IWP the information has to be sent back to the server.
Submit=script step Commit Record/Request
I found the problem, thank god!
