Error Importing Requesters

Error Importing Requesters

I am attempting to import approximately 1000 requesters.  When the import completes the system only imports about 600 entries and rejects 400 entries.  When I look at the "Failed CI List with Errors" it lists an error for many of the records as "Null".  I cannot determine what field the system is talking about, the rejected records look fine to me.  I can send the actual import files if needed for further examination
