Swing Door Locked Text?

[Amnesiaplayer]

Thanks... but i got an other problem?
it says on the first time Unexpected token IF
and if i delete that there will come Expected ;
and if i do that it says Unexpected {
... Where do i have to play ?! and my first function is this :

SetEntityPlayerInteractCallback("CellarDoor", "GetSwingDoorLocked", false);

if(GetSwingDoorLocked2(<CellarDoor>) == true)
{
SetMessage("Sign", "CellarDoor", 0);
}
