Row source value list filter

[Ruegen]

Trying to filter a continuous form using an unbound combo box that is set with a value list

when the value changes I was hoping to filter the form to only show the blank records

Private Sub Text53_AfterUpdate()


If Me.Text53.RowSource = "Name" Then
Me.Filter = "SchoolName is null"
Me.FilterOn = True
ElseIf Me.Text53.RowSource = "Suburb" Then
Me.Filter = "SchoolSuburb is null"
Me.FilterOn = True
End If
End Sub

any suggestions?

Nevermind - removed .rowsource
