Why is it always equal to 0?

I've tried to make a script where you save the Values,** but, when i print the Value, it's always says the number 0...**

If i'm doing this wrong, or just put the Value creation in the wrong place, please tell me!

Spotchoice = {nil,game.ServerStorage.Leftbang,game.ServerStorage.Rightbang,game.ServerStorage.Straightbang,game.ServerStorage.Mohawk,game.ServerStorage.Leftbang}
Index = 1
function Click()
 Index = Index + 1
 local item= Spotchoice[Index]
 if Index >= 6 then
  Index = 1
 end

player = script.Parent.Parent.Parent.Parent.Parent.Character

if player:FindFirstChild("HairValue")== nil then
HairValue = Instance.new("NumberValue",player)
HairValue.Name = "HairValue"

end
    HairValue.Value=Index
        print (HairValue.Value)
