How to program a button this way?

[ctccromer]

Rather than program "do [this] when the button is pressed down, do [that] when it's not pressed down", I want to program "do [this] when it's pressed, then do [that] when the same button's pressed again" and alternate between them. It would be really easy in a text based language but I'm a LabVIEW noob and don't know how to do it :/

I'm working with pneumatics. Basically I just need to give one Vi a value of 0 and another Vi a value of 1 when a button is pressed, and leave it that way even when I let go of the button. Then, next time I press the button, switch the two values. Then next time, switch them back, etc.

Pneumatics start retracted. Push button x to push the pneumatic arms out. Push button x again to pull the pneumatic arms back in
