Hi there.
I have an Infopath form that uses a submit option that will
1) synchronize information in a repating table with a sharepoint list, then
2) submit the form to a Sharepoint document library
Nothing too fancy. :-)
One of my users is having the following problem. I can't repro this problem myself and no one else seems to be having this problem.
She goes to the doc library and selects new> new document. She gets this message:
She clicks "update form," then she gets this error:

The template was created using Infopath 2010, but the server uses InfoPath forms services 2007, so it was saved as an InfoPath 2007 Filler Form Template. The user is running Windows 7 and InfoPath 2010.
I created a form for her in the document library, and she is able to edit it and submit it.
Thanks for your help!
