Help with DSUM using a named range with multiple criteria

I use the DSUM formula to count the rows associated with a specific Day/Week/Dept/Person criteria.
I'm using the following DSUM formula with a named range which works just fine with a single criteria:

=DSUM(Table,ActHrs,R.FRED_MON)


The named range is: =ActualHrs!$AN$64:$AQ$65
The cells for the named range are:

Day Week# Department ResourceName
Monday 22 *325* *royf*

What I want to do is be able to search for multiple departments. So I would want 325 OR 326 to be the department criteria. I've tried several different things here but am having no luck. Any help would be greatly appreciated!!

To include multiple criteria in a DSUM, you need to add another row to the criteria range. i.e. change the named ActHrs range to
=ActualHrs!$AN$64:$AQ$66

The criteria would become

Day Week# Department ResourceName
Monday 22 *325* *royf*
Monday 22 *326* *royf*

BE CAREFUL - if you leave the second row blank, then the DSUM includes all data!
