Check out the comment below that code. "limit switch on the forward motor direction"

What this example does is allows you to move the motor in either direction, but it tests for a special case for when the joystick is pushed forward (forward values are inverted, and give you a negative value instead of a positive). If the driver is holding the joystick forward, it will allow the motor to go up until the point where the limit switch is hit. The driver has the ability to drive the other direction (reverse) all day long, as the limit switch is disabled, and will not disable the motor value.

Q: So why is the False end of the Select connected to the joystick?
A: The False of the the select is connected to the joystick to control the motor speed.

Q: What is the default state for the Select?
A: The default state is False, where the motor value is directly connected to the joystick.

Q: What causes the Select to switch to the True case to turn the motor off?
A: Having the joystick pushed forward (where the value is less than 0) AND when the limit switch is depressed will cause the Select to switch to the True case, passing a 0 motor value, ultimately turning the motor off.

As RufflesRidge mentioned, this is only a small part of your problem, but this is the problem that will cause you to rip an appendage off of your robot via programming. Trust me, the mechanical guys will not be happy.

You need some while loops, and timers would be useful to maintain a good connection to the field.

Please get out of the mindset that your code works perfectly in teleop. In fact, I bet it does work perfectly, but you are using a joystick to control the motor instead of a constant value. Another problem is that you are probably going to turn the motor in the wrong direction if you think the code will work. You might want a -1 in there instead of a 1, which would make your code work, but why go through the extra effort of checking if a constant (constant meaning that it won't change, ever) goes negative?

Being able to copy someone else's code is one thing but being able to actually understand what the code is doing is another.

You have multiple issues, and I haven't seen one addressed since last night. I'd be happy to help you out if you want, but you'll have to just trust me on everything that I say. Send me a PM.
