When you say something spasific in chat a door will open?

local msgwanted = "INSERT TEXT HERE" --What they have to chat
local door = Workspace.door --Where ever it is.
game.Players.PlayerAdded:connect(function(player) --PlayerAdded, gets that player.
    player.Chatted:connect(function(msg) --Checks what the player says.
        if msg == msgwanted then --If they chatted the message wanted
	    	print("msgwanted is true") --Making Sure
		door.CanCollide = nil --or false
		wait(timeopen) --waits the time open
		door.CanCollide = true --Nobody else
	end
    end)
end)

There you go. I feel like I just gave you the script.
