I am making a flying mod but when I test it, it doesn't work. What's the problem?

var GemFly = 500;

  function useItem(x, y, z, itemId, blockId, side, itemDamage, blockDamage) {
    if (itemId == 500) {
      Player.addItemInventory(500, -1);
      Player.setCanFly(1); clientMessage("You feel the power of flight rushing through your veins!"); Entity.addEffect(getPlayerEnt(), MobEffect.jump, 7800, 1001, false, false);
	for (time = 0; time<= 6000; time++) {
          
          if (time == 1200) clientMessage("You have 4 minute left!");
          if (time == 2400) clientMessage("You have 3 minute left!");
          if (time == 3600) clientMessage("You have 2 minute left!");
          if (time == 4800) clientMessage("You have 1 minute left!");
          if (time == 6000) {
            clientMessage("The powers of flight leaves your body");
            Player.setCanFly(0);
          }
        }
      }
    }
}

This is the code for my Flying Mod. However, when I try to activate it, it does not work or consume the item. What is wrong with the code? Thanks!

P.S. What is suppose to happen is when I tap the gem(Id=500) on smth, it activates flight for 5 minutes.

function useItem(x, y, z, itemId, blockId, side, itemDamage, blockDamage) {
    if (itemId == 500) {
      Player.addItemInventory(500, -1);
      Player.setCanFly(1); clientMessage("You feel the power of flight rushing through your veins!"); Entity.addEffect(getPlayerEnt(), MobEffect.jump, 7800, 1001, false, false);
	for (time = 0; time<= 6000; time++) {
          
          if (time == 1200) clientMessage("You have 4 minute left!");
          if (time == 2400) clientMessage("You have 3 minute left!");
          if (time == 3600) clientMessage("You have 2 minute left!");
          if (time == 4800) clientMessage("You have 1 minute left!");
          if (time == 6000) {
            clientMessage("The powers of flight leaves your body");
            Player.setCanFly(0);
          }
        }
      }
    }
}

function modTick() {

if(canFly == true) {

time++;

if (time == 1200) clientMessage("You have 4 minute left!");

if (time == 2400) clientMessage("You have 3 minute left!");

if (time == 3600) clientMessage("You have 2 minute left!");

if (time == 4800) clientMessage("You have 1 minute left!");

if (time == 6000) {

time = 0;

canFly = false;

clientMessage("The powers of flight leaves your body");

Player.setCanFly(0);

}

}

}

function useItem(x, y, z, itemId, blockId, side, itemDamage, blockDamage) {

if (itemId == 500) {

Player.addItemInventory(500, -1);

canFly = true;

Player.setCanFly(1); clientMessage("You feel the power of flight rushing through your veins!"); Entity.addEffect(getPlayerEnt(), MobEffect.jump, 7800, 1001, false, false);

}
