SetFocus is getting ignored - Why? - vba

Question

I have 2 fields - txtTR1_Unit and cmbTR2_Unit. Together, these 2 fields represent the total UNIT.
cmbTR2_Unit has a list of unique values that when selected - txtTR1_Unit automatically gets the related value.
I've created a function called Tier1from2 - that accepts a 'string' and returns the related Tier1 value.
So when I update cmbTR2_Unit in my After_Update event, I'd like to automatically tab to the next field. - Another combo box. I figured that I shouldn't need to set any focus, because it would automatically go to the next field after updating.
txtTR1 gets updated just as expected from my Function, but then it just sits there and won't go to the next field. So I have attempted to 'SetFocus' to the next field after the update.
Still no go. What did I miss??
Private Sub cmbTR2_UNIT_AfterUpdate()
If Len(Me.cmbTR2_UNIT.Value) <> 0 Then
Me.txtTR1_UNIT.Value = Tier1From2(Me.cmbTR2_UNIT.Text)
'cmb_CostCenter.setfocus - 'this doesn't seem necessary - but it doesn't work anyway.
End If
End Sub
As a test I tried removing the function "Tier1From2(Me.cmbTR2_UNIT.text)" simply hard coding the word 'RESULT' in txtTR1_UNIT and it works without a hitch. I know I used to write a more simple function but I haven't touched VBA in awhile - How can I simplify this function:
Private Function Tier1From2(strTier2 As String) As String
Dim qdf As DAO.QueryDef
Dim db As DAO.Database
Dim strQry As String
Dim rs As Recordset
Set db = CurrentDb
Set qdf = db.QueryDefs("qUNIT_HUB")
strQry = "SELECT Tier1_Unit, Tier2_Unit " & _
" FROM LTBL_Cost_Collector " & _
" GROUP BY Tier1_Unit, Tier2_Unit " & _
" HAVING (((Tier2_Unit) = '" & strTier2 & "'));"
qdf.SQL = strQry
db.QueryDefs.Refresh
Set rs = db.OpenRecordset(strQry)
Tier1From2 = rs![Tier1_Unit]
Set db = Nothing
Set qdf = Nothing
Set Recordset = Nothing
End Function

Answer 1

It turns out that something in this function was causing the field and form to loose focus. db.QueryDefs.refresh perhaps? The solution was to update my Function as follows
Private Function Tier1From2(strTier2 As String) As String
Dim rs As DAO.Recordset
Dim db As DAO.Database
Dim strSQL As String
Dim strTier1 As String
Set db = CurrentDb
strSQL = "SELECT Tier1_Unit, Tier2_Unit " & _
" FROM LTBL_Cost_Collector " & _
" GROUP BY Tier1_Unit, Tier2_Unit " & _
" HAVING (((Tier2_Unit) = '" & strTier2 & "'));"
Set rs = db.OpenRecordset(strSQL, dbOpenDynaset)
strTier1 = rs!Tier1_Unit
Set rs = Nothing
Set db = Nothing
Tier1From2 = strTier1
End Function
This worked without a hitch.
