Variables for a Keypad
I was getting along with variables so well. Had everything working the way I wanted. But now? I've run into a brick wall.
What I want to do is have a numeric keypad on screen, which, when you click a number on the keypad, will appear in a window at the top. That's all well and good for individual numbers, but if I press a 1 and then a 2, it won't add the 2 beside the one, obviously, it will replace it.
I've thought and thought and thought about it, and the only solution I can come up with at the moment is creating a variable for any number combination possible, which would be incredibly tedious and take eons. Are there any other options, or should I scrap the idea?
I've done some searching on the forums here for ideas for a calculator, and I'm hoping for some other option besides finding a Flash calculator.
