How to keep track of which checkboxes are checked

Question

I have 21 checkboxes on a scene and want a user to have to
pick at least four of them, i will then use the ticked checkboxes
to bring data back from a database. My question is how do i keep
track of which checkboxes are clicked so i can put them in to a sql
statement like this?
select * from table where title in (checkbox1, checkbox2,
checbox13);
And how do i make sure the user has picked four boxes before
being allowed to leave the current frame?
EDIT: sorry this is probably in the wrong forum it should go
under basics, but instead of posting the thread there can someone
please reply to it here, thank you.

i am using flash component checkboxes, i tried to come up
with my own way to do this i am doing different:
on CheckBoxState -- name of custom handler
TickedBoxes = [] -- a empty list will be filled where ever a
checkbox is ticked
CheckBoxNames = ["dr no", "from russia","goldfinger",
"thunderball", "you only live" ]
-- the above is a list containing the names of all my
checkboxes
repeat with i = 1 to 5 - repeat for each checkbox
CurrentCheckbox = CheckBoxNames
-- used to keep track of which box is checked this sets
currentcheckbox to value of i, i is a checkbox from checkboxname
list
if the hilite of member(CurrentCheckbox) then -- if
currentcheckbox hilite is true (checked)...
append(TickedBoxes, CurrentCheckbox) -- ... add
currentcheckbox to the tickedboxes list
end if
end repeat -- end repeat
return TickedBoxes -- return the list of checked boxes
end
on mouseUp me -- on mouse click
choosenBoxes = me.CheckBoxState() -- chosenboxes is a
variable calls the handler on it
-- will put sql here
end
this is the only script i have which is attahced to my
submit button, but for some reason when i try to trace the results
in the message window it always return void can anybody tell me
what i am doing wrong?
