I have suggestion only: you should populate them dynamically. You may create 3 recordgroups. 1st for continets, I suppose it may be hardcoded. 2nd for countries, the where clause of query is based on the value of continets combo, and the third for provinces, the same way as for countries. Now you may create WLC triggers to call appropriate populate_group and populate_list. Regards, Dima
