Making a lever unlock a door?

[FlawlessHappiness]

void OnStart()
{
SetEntityConnectionStateChangeCallback("LEVER", "LEVER_CALLBACK");
}

void LEVER_CALLBACK(string &in asEntity, int alState)

{
if(alState == 1)
{
SetGlobalVarInt("OPENDOORINT", 1);
}
}

In the other level:

void OnEnter()
{
if(GetGlobalVarInt("OPENDOORINT") == 1)
{
SetSwingDoorLocked("DOOR", false, true);
}
}
