It's really bunch of problems:
1. Fox message tells you that you cannot order by Memo field (Iguess location is Memo).
2. Also what is This.Location?? It will be understood as custom property of active form. Otherwise you should put something else like thisform.txtBox1.value or even better add line:
cLocation=thisform....
and use it in SELECT.
