Here's a crude approach (untried).
Assumes none of these groups will ever have more than 9 buttons.
To build the value, have a mouseUp handler in each of the groups
something like this:
on mouseUp
if the owner of the target is me ## make sure the click was in the group
put 0 into tVal
put the hilitedButton of group 1 after tVal
put the hilitedButton of group 2 after tVal
put the hilitedButton of group 3 after tVal
put the hilitedButton of group 4 after tVal
# do whatever with tVal
end if
end mouseUp
Then to later retrieve the setting of any group using the calculated value:
function getGroupValue pVal, pGroup
## pVal is the value calculated above, pGroup is the group number
return char pGroup of pVal
end getGroupValue
I expect there are better and more general solutions, but it should work.
