>>Actually not similar to your solution. If you're doing a complete reselection of SQL what the requery() is for ? I'd simply assign SQL once in init and requery() when params changes. You could also do an index in init once and only requery()+seek in ChangeTown.

No you don't. Check FoxyClasses MoverListXX sample. Combos there use SQL rowsource assigned once in init and dynamically change content + what's selected based on selections related in another combo. ie: If you select 'Brasil' as country you get 'Sao Paulo' in city list and could select it. If you go back to country and select 'All', 'Sao Paulo' remains selected. If you choose 'Germany', city list selection resets.

Yes if you don't use listboxes :) Again check FoxyClasses MoverListXX sample.
