how to make a door load another map ?

[Crypto]

It gave me an error
: FATAL ERROR: Could not load script file 'custom_stories/maps/custom_stories/maps/maps/MansionEscape.hps'!
Main(24,1) : ERR : Unexpected token '{'

here is the script:
////////////////////////////
// Run when entering map
void OnEnter()
{
AddUseItemCallback("", "key_tomb_1", "castle_2", "KeyOnDoor", true);
}

void KeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("castle_2", false, true);
PlaySoundAtEntity("", "unlock_door.snt", "castle_2", 0.0f, true);
}
void OnStart()
{
AddEntityCollideCallback("Player" , "ScriptArea_1" , "MonsterFunc1" , true , 1);
}
void MonsterFunc1(string &in asParent , string &in asChild , int alState)
{
SetEntityActive("servant_grunt_1" , true);
AddEnemyPatrolNode("servant_grunt_1","PathNodeArea_1",0,"");
AddEnemyPatrolNode("servant_grunt_1","PathNodeArea_12",0,"");
}

{
ChangeMap(string& asMansionEscapeTwo, string& asStartPos, string& asStartSound, string& asEndSound);
}
