hps file scripting errors *i need helpX|*

[Bludsik]

I was able to fix most of the errors myself, (first time coding )
I'm really failing at this please someone help

The error reads: FATAL ERROR: could not load script file (blah blah...)
main(6,1):ERR: Expected ',' or ';'
main(18,12):ERR: Expected identifier

Here is my current script in my .hps file...
void OnStart
(
AddUseItemCallback("", "key_1", "door_1", "FUNCTION", true)
)

void OnEnter()
(

)

void OnLeave()
(

)
void FUNCTION(string &in item, string &in door)
(
SetSwingDoorLocked("door_1", false);
RemoveItem("key_1");
