Motors not working?

Me and my partner can’t seem to start the motors; we have the digital world x4 RobotC… we have tried all the buttons and typed ever possible code, but nothing seems to get the motors working. Any suggestions??

She also can’t drive forward even when the command is "(4.20, rotations, 50). Is this a different problem or do they both have to do with the motors not working?

Without more information it’s hard to know what the problem may be.
use a very simple program to verify one motor is working and then build upon that.

#pragma config(Motor,  port1,           motor_1,       tmotorVex393_HBridge, openLoop)
//*!!Code automatically generated by 'ROBOTC' configuration wizard               !!*//

task main()
{
    while(1) {
      motor motor_1 ] = vexRT Ch2 ];
      wait1Msec(20);
    }
}
