Java adding value to existing value (int)

Question

So I'm making this lottery game for practice and I'm almost done (I'm a beginner of java, needed alot of help to get this far). The final thing that I need before it's finished is to find a way for my "bank" to not reset each time the game is played.

The game is a lottery, each time you press a button you win or lose and that amount is supposed to be added or subtracted to or from your bank. But instead it simply replaces what is already in the bank. This is the code for the entire game and here is also a picture of what it looks like:
