Disabling Keypaay for darkrp

[Naimor65]

Hi.

I'm trying to disable the use of numpad in my darkrp but this code doesn't work i dont know why

concommand.Remove( "+gm_special" )
concommand.Remove( "-gm_special" )
concommand.Add( "+gm_special", function( ply ) ply:ChatPrint( "Numpad is disabled!" ) end )
concommand.Add( "-gm_special", function() end ) -- to avoid errors,
