Scripting Problem

[amnesiaplayer321]

Hi.I am looking forward to create a new custom story for amnesia.But i have problems with my script.And i see nothing wrong.And when i launch my story,it gives that error:
FATAL ERROR: Could not load script file
'custom_stories/mystory/maps/lvl1.hps'!
main (17, 21): ERR :Unexpected end of file
My script file:

////////////////////////////
// Run first time starting map
void OnStart()
{
AddUseItemCallback("", "Key", "Mansion_door", "UsedKeyonDoor", true);
AddUseItemCallback("", "Key2", "Door2", "UsedKeyOnDoor", true);

void UsedKeyonDoor(string &in asItem, string &in asEntity)

{
SetSwingDoorLocked("Mansion_door", false, true);
PlaySoundAtEntity("", "unlock_door", "Mansion", 0, false);
SetSwingDoorLocked("Door2", false, true);
PlaySoundAtEntity("", "unlock_door", "Door2", 0, false);

RemoveItem("Key");
RemoveItem("Key2");

Whats wrong about it and how to i fix?
