This code should be part of the After Update event procedure of cboVerificationType, and this procedure should be in the code module of the form that contains this combo box:
Private Sub cboVerificationType_AfterUpdate()
Dim strForm As String
Select Case Me!cboVerificationType
Case "Single"
strForm = "SubFormSingle"
Case "Dual"
strForm = "SubFormDual"
Case "Kitchen"
strForm = "SubFormKitchen"
Case "Scales"
strForm = "SubFormScales"
Case Else
MsgBox "select the search type"
Exit Sub
End Select
DoCmd.OpenForm strFormName, acNormal, , , , acDialog
End Sub
