xml-dev - Validation Error

[John Martin <John.Martin@ncmail.net>]

I am validating this DTD:

<!ELEMENT SVC_DMVFUELTACS_USERGRP.INQ (FUELTACS, USERS?, USERGRPS?,
NCSB-REQ?)>
<!ENTITY % ncsb-req-data "EMPTY">
<!ELEMENT NCSB-REQ %ncsb-req-data;>
<!ENTITY % fueltacs-data "EMPTY">
<!ELEMENT FUELTACS %fueltacs-data;>
<!ENTITY % users-data "EMPTY">
<!ELEMENT USERS %users-data;>
<!ENTITY % usergrps-data "EMPTY">
<!ELEMENT USERGRPS %usergrps-data;>

And I am getting this validation error from the parser.

Parser fatal error at line 3, character 34.
C:\My Documents\XML\FuelTaCS_working\SVC_USERGRP_INQ.DTD:3:34:E: an
entity end in a token separator
must terminate an entity referenced in the same group

I don't see the problem.  I'd appreciate another pair of eyes.
Thanks,
John
