Populating a Combo Box with data from a query based on another combo box on same form

P: 119
I have a form with two combo boxes. The first, cboAccount, allows a user to select an account. Ideally, the second combo box, cboSubAccount, will allow the user to select a Sub Account from a list of Sub Accounts for the particular Account already selected in cboAccount.

In the SubAccount combo box 'Row Source' field I have the following query:

SELECT [Sub Accounts].[Sub Account], [Sub Accounts].Account
FROM [Sub Accounts]
WHERE [Sub Accounts].Account=Forms!frmReportFilter1!cboAccount
ORDER BY [Account];

When I load up the form, the behaviour works exactly as I want it to for the first Account I select. However, after that, regardless of which Account I select, the list in the SubAccount combo box corresponds to the first account selected, not each subsequent account selected.

Does anyone know how to modify the query so that the cboSubAccount list always relates to the currently selected cboAccount, not always the first cboAccount?

I figured that the problem was that the query was only being executed once, so I hunted around for a way of executing the query for that control based off an event. I implemented the following code:

Private Sub cboAccount_Change()
cboSubAccount.Value = Null
End Sub

Would be interested to know if anyone has a better solution for what I have been trying to implement, but otherwise I think I'm okay now.

No - because you've got it dead right.
