Filter query from access form using variable

I would like to limit the output of a query based on the value of a variable on an acces form.

I am sure the answer is simple but the syntax i don't know.

The original query is named qry_PDM_Measures and includes...

- Project Category
- Measure

The combo boxes i want to control are on a form named frm_PDM_Results.....

cboProjectCategory
cboMeasure

When a value is selected from cboProjectCategory i want to limit the list in cboMeasure to those measures where Me.ProjectCategory on the form is equal to Project Category in the query.

Any help most welcome.

Thank you.

This is called cascading combo boxes. In order to make this work, you must have a table where you have both sets of values. You need to set the RowSource for the 2nd combo to:

SELECT DISTINCT Measure
FROM qry_PDM_Measures
WHERE [Project Category] = Forms!frm_PDM_Results.cboProjectCategory

You then need to add code two two events, the first is to the cboProjectCategory_AfterUpdate event. it should look like:

Private Sub cbo_ProjectCategory_AfterUpdate

me.cboMeasure.Requery

End Sub

The other is in the Form_Current event. This will make sure that if you go to a record that already has values in those fields, the combo box will display the correct list of items for the already selected Project Category

Private Sub Form_Current

me.cboMeasure.Requery

End Sub

Hello Jeff,

I am not an access programmer as you may have gathered, i am just a person that likes to dabble for fun now and again but i do like to see who is doing well in the league table.

Hello Fyed,

The result earns the points thats for sure but can you just add one tiny extra bit to the criteria

....And WHERE [Measure] <> Forms!frm_PDM_Results.cboProjectCategory....

or something similar

Regards

Solved, just a couple of bracket problems

WHERE (([Project Category] = Forms!frm_PDM_Results.cboProjectCategory) And ([Measure] <> Forms!frm_PDM_Results.cboProjectCategory))

Will post the points now

Regards
