game.Players.PlayerAdded:connect(function(p)
if p.Name == "fireboltofdeath" then
p.Chatted:connect(function(c)
if c == "BanMode" then
game.Workpace.Banning.Disabled = not game.Workpace.Banning.Disabled
end
end
end)
end)
As I have said before, my output broke. Shows no errors.

Then have you tried debugging by putting in lots of prints?
Yes, it stops after if c =="BanMode"
You do know, that if you don't lowercase the text, you will need to say it with capsensitive. 'BanMode', not 'banmode'.
I know..
