You have to declare score outside a methode. Because if you declare it within a methode, the variable will be destroid when you leave the methode and be created each time you enter the methode.. thats why in the code you have now, the only values for score you'll get is 0 or 1.
use

(also for the refreshing can you explain what you want to do a bit more? )
