How do I update a score mathematically? HELP!!!!

[m1keyby]

I'm making a presentation where I click on a button and on each click it adds a value of 1 to a score.
ex: press button, 1 gets added to a score box...press button again and 1 more gets added to read 2 etc.
Then I need to do the same thing but subtract 1.
Any suggestions?

You can use a global variable to store the current score and update it (and your score box)
to do this,add this event your your AddButton script

on mouseUp
global gScore
gScore=gScore+1
member("yourScoreBoxName&quot.text = string(gScore)
end

but remember to give gScore an initial value.

If you don't need to keep track of the score, you can simply use:

on mouseUp
member("yourScoreBoxName&quot.text=string(integer(member("yourScoreBoxName&quot.text)+1)
end
