=DCOUNT("Date", "qry", "[Field] = '30551'")

or, if [Field] is numeric:

=DCOUNT("Date", "qry", "[Field] = 30551")
0

Or maybe:

=IsNull(DCOUNT("Date", "qry", "[Field] = 30551"),0)   ' [Field] is numeric

=IsNull(DCOUNT("Date", "qry", "[Field] = '30551'"),0)   ' [Field] is string

Using the solution above.

@eghtebas,

You don't need to use the NZ() function (IsNull is the SQL Server equivalent) with DCOUNT( ) because it will always return a value, unlike DLOOKUP( ) which could return a NULL and therefore need the NZ( ) function wrapper.
