VEX Motor Not Working in Auton

I am coding an autonomous and the drivetrain and other motor work but the conveyor doesn’t work. It works in driver control though. I don’t have the laptop with the code on me but the code is;

Drivetrain.driveFor(forward,1090,mm)
StakeClamp.spinFor(reverse,8,turns)
ConveyorMotor.spin(forward)

States is on the 15th and we need to finish this and plan on doing a programming skills so please let me know how to fix this :pray:
