[SCRIPT] Normal Door 'Locked Text

[FlawlessHappiness]

if that is your whole .LANG file then it's wrong.
But the entry and the script looks fine

Though if you write it like that, it will say dinner door at every door that is locked (where you put the script).
Why not instead write "It's locked", and then give the player a quest: AddQuest (Which is a memento), that says "I need a key to enter the Dining Room."?
That would be better i think
