ServerStorage is not a valid member of DataModel?

Why do I keep getting the error named in the title?

local box = script.Parent.TwitterCode
local player =  


function onClick()

if box.Text == "OP3NING" then
    wait(1)
    box.Text = "Valid!"
    local s = game.ServerStorage.Sparkles:Clone()
    s.Parent = player.Torso
    wait(3)
    box.Text = "Twitter Code"
else

    box.Text = "Invalid!"

    wait(3)
    box.Text = "Twitter Code"

end
end

script.Parent.MouseButton1Click:connect(onClick)
