Controlling drop-downs in one form base dupon the values submitted in a prior form

For some reason, I cannot get this to work. Basically, I have a table "state" that has two fields, "state" and "region." I want to limit the values that show up in the state drop down to a specific region value.

So, my form has only one drop-down called "State." I use the following query to populate "State:"

SELECT State.State FROM State ORDER BY 1

This form is accessed by first hitting a fporm where you select the given region from a drop down. The name of the drop down is "Region" and it's event looks as so:

Private Sub LaunchStateButton_Click()
On Error GoTo Err_LaunchStateButton_Click

Dim stDocName As String
Dim stArgValue As String
Dim stOpenCriteria As String

stDocName = "frmSelectState"

If IsNull(Me![Combo2]) Then
MsgBox "Please Select a Region"
Else
stArgValue = Me.OpenArgs & "|" & Me![Combo2]
stOpenCriteria = "[Region]='" & Me![Combo2] & "'"
MsgBox stOpenCriteria

DoCmd.OpenForm stDocName, , , stOpenCriteria, , , stArgValue
DoCmd.Close acForm, Me.Name
End If
Exit_LaunchStateButton_Click:
Exit Sub

Err_LaunchStateButton_Click:
MsgBox Err.Description
Resume Exit_LaunchStateButton_Click

End Sub

For some reason, this code simply does not work. Do I need to do anything special in either form to tie the event in the region form to the drop down in the state form?

Needless to say, I'm a newbie to VBA and would appreciate any help I can get. Thanks.

The form is in access??

I'd use one form and requery the second combo list on it (whenever the first combo has changed).

Other than that, looks ok. Is there code on the second form to filter the argument list?
