Select system help?

I don't know why this script not working automatically... Can help someone? I have 2 scripts.. First script: Selecting (example item) button

local select = script.Parent.Parent.Parent.Selected -- StringValue

function Select()
	select.Value = "Item1"
end

script.Parent.MouseButton1Down:connect(Select)

Second script: Detect selected item and config for buy button and something... (localscript)

local select = script.Parent.Selected
local Image = script.Parent.ImageLabel
local Des = script.Parent.Text
script.Parent.Selected.Changed(function(select)
	if select == "Item1" then
	Image.Image = "http://www.roblox.com/asset/?id=285779644"
	Des.Text = "Bla"
	elseif select == "Item2" then
	Image.Image = "http://www.roblox.com/asset/?id=285779644"
	Des.Text = "Bla"
end)
