Making a lever unlock a door?

[Wyz]

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);
}
}

Thanks! For that if statement, is the alState on the lever all the way up or down? And the global variable gets declared in an HPS file in the maps folder called 'global'?
