I found the issue. There was a space in the "firstname" field and the comma separator for that field in some of the entries.
The problem with the date upload still persists however. I've tried just straight text "12012014" using the (mm-dd-yyyy) format, I've tried "/" and "-", but still no upload. Are there any settings in CB Configuration that could be adjusted? I have the date format to display as both mm/dd/yyyy and mm-dd-yyyy, but no change.
