Making A Jeopardy Game

[minfootball]

I am making this game for a teacher to give to students on an individual lvl

i am still planning but my school is new to alice and several problems have been noted

is there anyway to make a pointsystem so that when an answer is correct it add s or subtracts the value from the users score?

also is there a way to set a paramater that when ever a certain object (game tiles) are clicked that they do a certain method?

other then these to details i can pretty much see how i am going to do the rest of the game. thx for any help.
P.S. if u could write me a code as an example this is not homework or extra credit or even a project this is just a favor for a teacher
