well, almost :-)

In each handler you have to declare the global before you use ist:

on openStack
     global gUserpoints
     put 0 into gUserpoints
end openStack

Not necessary, see above

Yes.

> And if its a point awarding button

on mouseDown
    global gUserpoints
    add 10 to gUserpoints
end mouseDown

Simply manage a global "inventory" list, too, where you store the  
names of all cards
(If i get it right, you can only get ponts on cards? Anyway, the  
principle will be the same.)
that can "give" points and have been cklicked.

Of course you will have to give meaningful and unique names to your  
cards then!

Then you can check each time before you add points.
Don't worry the chekcing will be almost immediately, even for very  
long lists ;-)

To use your examples above:

on openStack
    global gUserpoints
    put 0 into gUserpoints
    global inventorylist
    put empty into inventorylist
end openStack

...
on mouseDown
## Why not use mouseUP?
##That will give the user a chance to make up his mind! ,-)
    global gUserpoints
    global inventorylist

   if the short name of this cd is not among the lines of  
inventorylist then
     put the short name of this cd & CR AFTER inventorylist
    ## build a RETURN delimted list of all point awarding cards to  
check against!
     add 10 to gUserpoints
   else
     beep ## or whatever. Optional!
   end if
end mouseDown

Know what I mean?
Drop a line if you need more info/help!
