When you press your buttons, you should be able to see the small green LEDs changing on top of the solenoid breakout board. Are you seeing that?

The problem with your code looks like it might be in the for loop.

You start with indexVar=1 and exit the loop if indexVar is > 2, so you will only check indexVar values of 1 and 2 but you have cases where it looks like you want to check up to 12.
