Autonomous is not working!

[sistamatik5583]

We're in a bit of distress due to the fact that our Autonomous isn't working. Every time we change the code, the robot just jerks forward and stops moving. I've tried several different things but they all do the same thing-- it jerks forward about an inch and then completely stops. We've tried while loops, flat sequence, tried changing the times for the timers and the numbers for the motors and even tried the default code it gave us to begin with.
Here's the current code:


Any ideas as to what we're doing wrong? Any help is very much appreciated!
