Bit of coding help

[SoulSaber1]

So, for autonamous we are using a modified line tracker code, with certain cases for different scenarios. After this loop we want the robot to go backwards, but we can't seem to make it happen.

case 7: //ALL SENSORS ON *OR* MAYBE AT CROSS
                        if (time > stopTime)
                        {
                            atCross = true;
                            speed = 0;
                            gripper.set(false);         //Closes gripper
                            gripper2.set(true);         // "     "
                            while (backCount < 5)
                            {
                                backCount++;
                                drive.arcadeDrive(-.5,0);
                            }
                        }

Any ideas?
