InfoPath Dev

Did you change the settings in FORM OPTIONS/COMPATIBILITY to "Design a form template that can be opened in browser or InfoPath" and add the URL?

The error went away once I configured the SUBMIT options.  So now, my form says "successfully submitted" but data doesn't show up in my form library (even though I promoted the fields).  ??  

Submitting to the SharePoint library still doesn't display the submitted data though.  I don't understand why SAVE shows my data, but submit gives me an error!   :(

I've been working on this one for weeks and still can't get it to work!  I can get it to show the form in my form library (and save even), but it won't allow submit. Do I send the data to the SharePoint Document Library or to a web service?

I have been locked out of my InfoPath form and I keep getting this message: The form definition (.xsf) file cannot be opened because of an error. The file cannot be validated by the XML Schema. 'DBA Requirements List' is a duplicate key for the unique Identity Constraint ...
