  Motor.setSpeed(200);
  Motor.run(RELEASE);

}
void loop(){
  if (switch(results.value)) = (case 0xFF906F:){     // THE OTHER PROBLEM <-------------
    Motor.run(FORWARD);
  }
  else switch(results.value) != (case 0xFF906F:){    // THE PROBLEM <-------------
    Motor.run(RELEASE);
  } 
  
  
}

The problem is the if and else switch lines, The else switch line was, "else if switch(results.value) != (case 0xFF906F:){" but I changed it to "else". I need help I'm relatively new. What I am trying to do in the code is making it so if the receiver revives the information "case 0xFF906F:" then it performs and action with a motor, if the button is not being pressed anymore on the remote then the motor stops.
