Chief Delphi - Spike relay mapped to gamepad trouble.

First, let me preface this with this : I am teaching myself java (uh-oh) I'm a mechanical mentor/ flight engineer who has only programmed HTML back when it was new (yikes!) closest to java I've ever been to was DHTM (remember that?).

I'm helping to start a new team to the north and I'm going to be relied upon to help teach the control system / programming among other things (everything else). It's my weakest area so I've decided to dive in. I've set up a complete control board in my dining room (- brownie points) as well as maybe a smallish robot I'm building as a demo bot (already has a weight problem).

The problem I'm having is I mapped button 1 (A button) of a gamepad to turn on the spike (kOn) when pressed, and off at all other times. It worked. the problem now is I can't map it to any other button - I can try to map it to 2, or 3, or 4, push the code, re boot the c-Rio, power cycle, it's like button 1(A) has been hard wired to the spike on. even if I comment it out and push the code it still works?? :ahh:

attached is my very simple spaghetti code - I'm sure its probably something I'm missing (hopefully obvious to all of you. right now it has a left side and a right side drive to 4 can jags (which works just fine). My woes are with this relay. I have named the relay "light" as if it were actuating a light, which in this case all I've been doing is watching the state light on the spike itself.

here is the code.

Thanks for taking a look, hopefully I can figure this out. seams odd that I was able to program it in (didn't do it before I added the programming) but now its all it wants to do - and its a bit :confused: .

The gamepad we are using is the logitech rumble F510 if that matters.
