(SOLVED) Attempt to concatenate Instance with string?

Hello, I am making customization for my RC car game. But the sign that says the power doesn't work. I get the error attempt to concatenate Instance with string. I don't know what that means?

local speed = game.Workspace.Values.ElectricPower
while wait() do
	script.Parent.Text = speed .. " Electric Power"
end

Nevermind I just had to add .Value again...lol.
