Problem with Custom commands!

[YesJelly]

function forums( ply )
	ply:SendLua('gui.OpenURL( "http://thenexushub.net/index.php" )')
end

function donate( ply )
	ply:SendLua('gui.OpenURL( "http://*********com/pql2uss" )')
end

function join_dr( ply )
	ply:SendLua( 'RunConsoleCommand( "connect" ,"193.0.159.202:27465" )' )
end


hook.Add( "PlayerSay", "Commands", Commands )

function Commands( ply, text, public )
	if( string.sub( text, 1, 7) == "!website" ) then 
		print("used !website")
		forums( ply )
	elseif( string.sub( text, 1, 7) == "!donate" ) then
		print("used !donate")
		donate( ply )
	elseif( string.sub( text, 1, 4) == "!ttt" ) then
		print("used !dr")
		join_dr( ply )
	end
end

When I type it nothing happens.

Can anyone tell me why?
