I'm having difficulty filtering a form using a multiselect list box when using some Allen Browne code. I get the error "Syntax Error (missing operator)in query expression '([City] IN (""Sydney"London)'. - when I filter the cities Sydney and London from the multiselect list box in the form. The list box multiselect is set to Simple. The code breaks at Me.Filter = strWhere four lines from the end. Thanks for looking!
