Unexpected Token

[ZeMaster091]

This is my .hps

////////////////////////////
// Run first time starting map
void OnStart()
{
AddUseItemCallback(""e, "hollow_needle_1", "First_Door", "UsedKeyOnDoor", true);
}
void UsedKeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("First_Door", false, true);
PlaySoundAtEntity("", "unlock_door", "First_Door", 0, false);
RemoveItem("hollow_needle_1");

}

{
AddEntityCollideCallback("Player", "SlamDoor", "CollideRoomTwo", true, 1);
}

void CollideRoomTwo(string &in asParent, string &in asChild, int alState)
{
SetSwingDoorClosed("First_Door", true, true);
}
////////////////////////////
// Run when entering map
void OnEnter()
{

}

////////////////////////////
// Run when leaving map
void OnLeave()
{

}

How can I fix this?
