how do i make my leg go on fire with a script?

c/f = Instance.new("Fire") f.Parent = game.Workspace.jacob4507.Head f.Size = 4 f.Heat = 25 f.Color = Color3.new(1,0,0) f.SecondaryColor = Color3.new(0,0,4)

local fire = instance.new('Fire')
fire.Heat = 4
fire.Size = 4
fire.Enabled = true
fire.Color = color
fire.SecondaryColor = color
wait(.1)
fire.Parent = game.Players.jacob4507.Character['LeftLeg']

Should work
