I just posted the array structure, here they are again: First time natsort($array) returns Array ( [0] => 02-11-2004|Salt Lake|UT|Wilkes-Barre|PA||No|No [1] => 01-23-2004|Salem|WA|Wilkes-Barre|PA||No|No [2] => 01-08-2004|Denver|CO|Wilkes-Barre|PA||No|No [3] => 01-02-2004|Wilkes-Barre|PA|Denver|CO||Yes|Yes [4] => 01-16-2004|Wilkes-Barre|PA|Salem|WA||Yes|Yes [5] => 01-30-2004|Wilkes-Barre|PA|Salt Lake|UT||Yes|Yes ) Second time natsort($array) returns Array ( [0] => 01-30-2004|Wilkes-Barre|PA|Salt Lake|UT||Yes|Yes [1] => 01-16-2004|Wilkes-Barre|PA|Salem|WA||Yes|Yes [2] => 01-02-2004|Wilkes-Barre|PA|Denver|CO||Yes|Yes [3] => 01-08-2004|Denver|CO|Wilkes-Barre|PA||No|No [4] => 01-23-2004|Salem|WA|Wilkes-Barre|PA||No|No [5] => 02-11-2004|Salt Lake|UT|Wilkes-Barre|PA||No|No ) Nothing has changed in the array, but the order. Why does this stuff always happen to me? lol Thanks, Jake McHenry Nittany Travel MIS Coordinator http://www.nittanytravel.com
