what do i change to fix "Torso is not valid a member of Model"?

hello - this is from a tutorial i'm trying to work through. Currently, I get one instance of the fireball, then Roblox throws error, "Torso is not valid a member of Model". I have this LocalScript is placed in StarterPack:

Enabled = true


Mouse.KeyDown:connect (function(key)
    if Enabled == false then return end
    key = key:lower()
    if key =="q" then
    Enabled = false
    Fireball = Instance.new("Part")
    Fireball.Shape = ("Ball")
    Fireball.Material = "Neon"
    Fireball.Parent = Character
    Fireball.CFrame = Character.Torso.CFrame*CFrame.new(0,0,-5)
    print("q")
    end
    Enabled = true

end)

Thanks for looking at this, Micy852
