Use MenuPick properly

Another way to do it that involves more SQL but less Livecode is

set the text of button xyz to revDataFromQuery(,,gDBID,"SELECT <datacolumn>
FROM <tablename> ORDER BY <datacolumn>")

set the cKeys of button xyz to revDataFromQuery(,,gDBID,"SELECT <keycolumn>
FROM <tablename> ORDER BY <datacolumn>")

I think I like that better, simpler and not likely to be be noticeably
slower.
