DLookup based on Query

[Guest]

Please help....Tired of trying diffferent ways nothing working.
Using sample of NW.DB Orders. It looks up the rate in Products

In my Service table (Which would be Products table), I have added taxes.
GST and PST.

based on the following

Private Sub ServiceID_AfterUpdate()
On Error GoTo Err_ServiceID_AfterUpdate

Dim strFilter As String

' Evaluate filter before it's passed to DLookup function.
strFilter = "ServiceID = " & Me!ServiceID

' Look up Service's unit price and assign it to UnitPrice control.
Me!UnitPrice = DLookup("UnitPrice", "Services", strFilter)



Exit_ServiceID_AfterUpdate:
Exit Sub

Err_ServiceID_AfterUpdate:
MsgBox Err.Description
Resume Exit_ServiceID_AfterUpdate

End Sub

Can I modify this to also on (After Update) hav thei look up the GST and PST
rate.

I have tried multiple things nothing works.......

Any help Please.......................Thank you.

' Evaluate filter before it's passed to DLookup function.
strFilter = "[ServiceID] = " & Me!ServiceID

If ServiceID is a text field, you need this syntax:
strFilter = "[ServiceID] = '" & Me!ServiceID & "'"

' Look up Service's unit price and assign it to UnitPrice control.
Me!UnitPrice = DLookup("[UnitPrice]", "Services", strFilter)
