vex robot not moving in game

when we were doing vex star struck the robot would stop working and not move when we started playing the game, then when we were not playing the game it would drive easily

does anyone know what this could be or how to fix this

Do you have it programmed in competition format? Do you mean while connected to feild control? Or while not lifting/scoring stars and cubes. We need more information

make sure your code is in the correct format and your remote is connected properly.

If you are having problems with converting your code to competition format then just post the code and I am sure we can help.
