access Dcount of yes no field

I have a form in a datasheet view.  I have a few txt fields where I use the Dsum function to show me totals on the form.  Ex: for the Finish column I use:

=DSum("[DrFin]","DoorTagLog","[BatchID] = " & [ID])
This sums up the values in the table DoorTagLog for the DrFin so I can see it in the Main form which is bound to the Main JobsDoor table.

I have a field in the DoorTagLog table that is a yes/no field called DrTagShip.  I have a txt field on my main form called "To Ship".

The ToShip =  number of finished doors - shipped doors.

I have the number of finished doors = DSum("[DrFin]","DoorTagLog","[BatchID] = " & [ID])

I am having a hard time getting the Dcount working to figure out how many doors have shipped. Here is what I have tried so far:

=DCOUNT("[DrTagShip]","DoorTagLog","[BatchID] = " & [ID] and "[DrTagShip] = '-1'")

It returns the same value in each row of the datasheet = 1699  -  I am trying to count the nunber of yes values for each Job.

Any suggestions?

Thanks for your help.

see the difference from your dcount

=DCOUNT("[DrTagShip]","DoorTagLog","[BatchID] = " & [ID] and "[DrTagShip] = '-1'")

revised dcount

=DCOUNT("[DrTagShip]","DoorTagLog","[BatchID] = " & [ID] & " and [DrTagShip] = -1")

johnmadigan,Just for reference, internally Access stores boolean True as -1.  Thus, [DrTagShip] = True and [DrTagShip] = -1 are equvalent tests.:)Patrick

Thanks - I knew I was missing something with the syntax - I love a quick fix.

I am usind the Dsum in the txt field of the datasheet - any advantages to  using a subquery in the main form query to do the same thing?

thanks again for the help.
