counting yes/no fields in a table

Hi, I need to count the number of times a field in 'table1' is true for a specific form 'id' (from table2).
This value needs to be stored as an integer.
Any ideas?
I have tried both of these but they return errors.
where table1 = ukcShapeData and table2 = ResearchInToDCD.

'Forms!ResearchIntoDCD![NoOfShapesPassed] = DCount("[ShapePassed] ", "[UKCShapeData]", "[SubjectNum] = Forms!ResearchIntoDCD![subject number]"And [UKCShapeData]![ShapePassed]=Yes)

Forms!ResearchIntoDCD![NoOfShapesPassed] = IIf(ShapePassed = Yes, DCount("*", "[UKCShapeData]", "[SubjectNum] = Forms!ResearchIntoDCD![subject number]"), 1)

You may have been close with your first attempt -

'Forms!ResearchIntoDCD![NoOfShapesPassed] = DCount("[ShapePassed] ", "[UKCShapeData]", "[SubjectNum] = Forms!ResearchIntoDCD![subject number]"And [UKCShapeData]![ShapePassed]=Yes)

However, the syntax needs work.  Try -

Forms!ResearchIntoDCD![NoOfShapesPassed] = DCount("[ShapePassed] ", "[UKCShapeData]", "[SubjectNum] = " & Forms!ResearchIntoDCD![subject number] & " And [UKCShapeData]![ShapePassed] = Yes")

The problem has been solved. The solution is

Forms!ResearchIntoDCD![NoOfShapesPassed] = DCount("[ShapePassed] ", "[UKCShapeData]", "[SubjectNum] = Forms!ResearchIntoDCD![subject number] And [UKCShapeData]![ShapePassed]=Yes")

If anyone else tries this.
This code works.
