Im currently making a roblox game based off Spray paint but the code does not seem to work...Can anyone help me?

This is what I got so far:
(Everything works fine except the other players cant see what you are drawing)
-- Toggle : [=] (enable / disable drawing)

-- Undo : [Z] (remove last drawn line in canvas)

-- Draw : [Left Click] (draw)

-- Clear : [F] (clear canvas)

-- Rainbow : [R] (toggle rainbow color drawings)

-- Neon Glow : [X] (toggle glowing drawings)

-- Other in GUI

-- Toxicity : [Q] (toggle toxicity aka kills people)
