infopath 2010 error

HI,

I am getting an error when i click the submit button.  This happens when i do a preview also.

I am using sharepoint list as my data source and am able to grab the data fields from sharepoint.  But when i try to submit i get an error. 

The form cannot be submitted because of an error.

  I can pull down the fields from sharepoint but cant submit the form.  I added the sharepoint site as a trusted site and set the settings to low.  

Any help will be greatly appreciated.  

Thanks,

michael
