Count Function Report Recs in Sub report

I have this in a sub report.

=Count(qryCARETSCustCities_LA.City) - this populates records in the main report.

I need to count the records in the main report which is populated by the query above and show that count in the sub report.

This just keeps coming up zero.

Bracketing =Count([qryCARETSCustCities_LA].[City]) produces an error

Directions anyone?

Thanks . . . Rick
