Hello -

I have the following Procedure:

Private Sub Course_IDFilter_Exit(Cancel As Integer)
Dim StringWhere As String           'The criteria string.
Dim lngLen As Long                      'Length of the criteria string to
append to.
     

    Me.Filter = "[Course_ID]=[Course_IDFilter]"
    Me.FilterOn = True

End Sub

The objective is to apply a filter to the data in the detail section of a
form for all records with [Course_ID] = to the number in the unbound
[Course_IDFilter] field after a course ID is entered into it.

The filter works, but I get an "Enter Parameter Value" window that asks me
to enter the [Course_IDFilter] value again.

What have I missed?

many thanks
