Perspective on code for motors and Robot arm

[Team 2524]

Drive: Tank Mode
Joysticks: 2 for Tank Mode
Number of Arms: 2 (1 big Arm and 1 little Arm)
Speed Controller: 2 Jaguars(2 motors for Big Arm)
1 Victor(Little Arm)
PWM channels: 1 & 2 for Drive motors
PWM channels:3 & 4 for Big Arm
PWM channel: 5 for Little Arm

Arm Movement: Y-Axis direction(correct me if I'm wrong)

Goal: Be able to press a button to switch from Drive motors to Arm motors. I want to have each joystick control an arm.

I posted the Begin.vi and Telop.vi to make it easier.
Also Pictures of Big Arm and Little Arm.
