Response to "Programming Help"

My fixed version of your code is below, and also the problem with yours may be that you’re using Btn7UXmtr2 (and D), which is only for the partner controller (you can use two controllers on one bot in VEX). If you’re only using one controller, use Btn7U and Btn7D.

#pragma config(Motor,  port2,           IntakeR,       tmotorVex393HighSpeed_MC29, openLoop)
#pragma config(Motor,  port3,           IntakeL,       tmotorVex393HighSpeed_MC29, openLoop)
#pragma config(Motor,  port4,           driveR,        tmotorVex393HighSpeed_MC29, openLoop)
#pragma config(Motor,  port5,           driveL,        tmotorVex393HighSpeed_MC29, openLoop)

#define LIFT_SPEED 120

void mobilelift(int speed)
{
	motor[IntakeL] = speed;
	motor[IntakeR] = speed;
}

//drive right void
void DriveLeft (int speed)
{
	motor[driveL] = speed;
}

//drive left void
void DriveRight (int speed)
{
	motor[driveR] = speed;
}

task main(){
  while(true) {
    DriveRight(VexRT(Ch3));
    DriveLeft(VexRT(Ch2));
    mobileLift(LIFT_SPEED * (VexRT(Btn7DXmtr2) - VexRT(Btn7UXmtr2)));
  }
}

Thnks it helped a lot.
