I'm working on a form "Add New Cst". On its field Name "TripNo" and Control source is "TripNo" Format Standard, decimal places = 0
On its BeforeUpdateEvent I'm getting a Run time error '3075;
Syntax error (missing operator) in query expression 'TripNo= &
[TripNo]';
I want this message not comes and it should check for Duplicate entry, Event is:
Private Sub TripNo_BeforeUpdate(Cancel As Integer)
Dim stLinkCriteria As String
Dim rsc As DAO.Recordset
'Don 't check if not on a new row
'If Not Me.NewRecord Then Exit Sub
stLinkCriteria = "TripNo= & [TripNo] " '"
Debug.Print stLinkCriteria
'Check Cst table for duplicate TripNo
If DCount("*", TripNo, stLinkCriteria) > 0 Then
'Message box warning of duplication
MsgBox "This Trip No: " & [TripNo] & " has already been entered" & vbCrLf & _
"at" & [TripNo] & "." _
, vbInformation, "Duplicate Entry"
'Undo duplicate entry
Me.Undo
'Go to record of original TripNo
Set rsc = Me.RecordsetClone
rsc.FindFirst stLinkCriteria
Me.Bookmark = rsc.Bookmark
Set rsc = Nothing
End If
End Sub

Please help where is the mistake.
