BTW, if you use code to set the controlSource, you probably should use the init() method...the activate() fires if the user leaves that form and sets focus back to it.

thisform.lstntm1.RowSourceType = 3
thisform..lstntm1.RowSource = [select name, TRANSFORM((rank/7)*100,"999%") as rank ] + ;
                                   [ from matches into cursor matchesCursor ]
