How to have more scripts then one at a time.[Solved]

[clock123]

Hey, when ever I add more then one script into my game files to my custom map it crashes, how should I fix that?, here's what I'm trying to add.

Spoiler below!

void OnStart()

{
AddUseItemCallback("", "Key1", "Door1", "KeyOnDoor", true);
}

void KeyOnDoor(string &in asItem, string &in asEntity)
{
SetSwingDoorLocked("Door1", false, true);
PlaySoundAtEntity("", "unlock_door", "door1", 0, false);
RemoveItem("Key1");
}

{
ConnectEntities("door_connection", //Name of connection
"Lever1", //Parent entity (Affects)
"Shelf", //Child entity (Affected)
false, //Invert the state sent
1, //States used (0=both), checked before invertion.
"CreateDust"); //callback
}
