Create Bulk Users fails - Error Code : 8007200b - The attribute syntax specified to the directory service is invalid.

Create Bulk Users fails - Error Code : 8007200b - The attribute syntax specified to the directory service is invalid.

I cannot understand why I'm getting the following error:

Error Code : 8007200b - The attribute syntax specified to the directory service is invalid.

See attached images documenting the process.  All looks good, but then the Logon Name information disappers!  Not sure if that is the problem, though.  Help!
