[AccessD] Expression not working in text box

=Forms!mainform!subform.Form.RecordsetClone.RecordCount
 
I've used the above expression before, in a main form, to return a count of
the records in a subform. It isn't working in 2003. It works in the
Immediate window, so I have no clue what the problem is. :( 
 
I know I can just use Count(*) in the subform and reference that control --
and I will if I have to in the end -- but anyone know what they above won't
work in 2003?
