Troubleshooting/Error: EXCEPTION: Field 'date_input' not found

Whenever I click the "Export" button on the marked records page, I receive the error: EXCEPTION: Field 'date_input' not found.  My marked records have dates of the format 9/5/2007 in that field, so that shouldn't be an issue, even if I also have the field on the web_post_hide list.  Any ideas what's causing me to receive this error?

Thanks,

Ben
