Can someone tell me what is wrong with our user control? We want the Intake to go out with tray when button b is pressed. the tray moves, but the intakes do not.
void usercontrol(void) {
// User control code here, inside the loop
while (1) {
// This is the main execution loop for the user control program.
// Each time through the loop your program should update motor + servo
// values based on feedback from the joysticks.
FL.spin(vex::directionType::fwd, (Controller1.Axis2.value()+Controller1.Axis1.value()), vex::velocityUnits::pct);
BL.spin(vex::directionType::fwd, (Controller1.Axis2.value()+Controller1.Axis1.value()), vex::velocityUnits::pct);
FR.spin(vex::directionType::fwd, (Controller1.Axis2.value()-Controller1.Axis1.value()), vex::velocityUnits::pct);
BR.spin(vex::directionType::fwd, (Controller1.Axis2.value()-Controller1.Axis1.value()), vex::velocityUnits::pct);
/*
FL.spin(vex::directionType::fwd, (Controller1.Axis3.value()), vex::velocityUnits::pct);
BL.spin(vex::directionType::fwd, (Controller1.Axis3.value()), vex::velocityUnits::pct);
FR.spin(vex::directionType::fwd, (Controller1.Axis2.value()), vex::velocityUnits::pct);
BR.spin(vex::directionType::fwd, (Controller1.Axis2.value()), vex::velocityUnits::pct);*/

//The Tray goes out with Button B and in with Button A.
if (Controller1.ButtonA.pressing ()){
Tray.spin(directionType::rev, 100, vex::velocityUnits::pct);
}

  else if (Controller1.ButtonB.pressing()){
      Tray.spin(directionType::fwd, 100, vex::velocityUnits::pct);
      IntakeL.spin(directionType::rev, 30, vex::velocityUnits::pct);
      IntakeR.spin(directionType::rev, 30, vex::velocityUnits::pct);

  }
  
  else{
      Tray.stop(brakeType::hold);
  }
  
  
  if (Controller1.ButtonL1.pressing()){
      Lift.spin(directionType::fwd, 100, vex::velocityUnits::pct);
  }
  else if (Controller1.ButtonL2.pressing()){
      Lift.spin(directionType::rev, 100, vex::velocityUnits::pct);
  }
  else{
      Lift.stop(brakeType::hold);
  }
  
  
  if (Controller1.ButtonR1.pressing()){
      IntakeL.spin(directionType::fwd, 100, vex::velocityUnits::pct);
      IntakeR.spin(directionType::fwd, 100, vex::velocityUnits::pct);
  }
  else if (Controller1.ButtonR2.pressing()){
      IntakeL.spin(directionType::rev, 100, vex::velocityUnits::pct);
      IntakeR.spin(directionType::rev, 100, vex::velocityUnits::pct);
  }
  else if (Controller1.ButtonDown.pressing()){
      IntakeL.spin(directionType::rev, 50, vex::velocityUnits::pct);
      IntakeR.spin(directionType::rev, 50, vex::velocityUnits::pct);
      FL.spin(directionType::rev, 20, velocityUnits::pct);
      BL.spin(directionType::rev, 20, velocityUnits::pct);
      FR.spin(directionType::rev, 20, velocityUnits::pct);
      BR.spin(directionType::rev, 20, velocityUnits::pct);

  }
  else{
      IntakeL.stop(brakeType::hold);
      IntakeR.stop(brakeType::hold);
  }

wait(20, msec); // Sleep the task for a short amount of time to
                // prevent wasted resources.

}

From what I see from your code.

WHEN this is runned!
else if (Controller1.ButtonB.pressing()){
Tray.spin(directionType::fwd, 100, vex::velocityUnits::pct);
IntakeL.spin(directionType::rev, 30, vex::velocityUnits::pct);
IntakeR.spin(directionType::rev, 30, vex::velocityUnits::pct);
}

What happens is the other if and else if and then else at the bottom that controls the intakes is messing it up.
else{
IntakeL.stop(brakeType::hold);
IntakeR.stop(brakeType::hold);
}

So basically it is constantly telling intakes too stop when you press button B because this else is not with that if, else if, else. Just add two else statements and fix your code up.
