Shirt & Pants not being added to the character when I call it? [Un-Answered]

I have made 2 scripts where they change a person's clothing to their according shirt, the only difference between the two is that one is for the Blue team and the other is for the Red team. I have placed both scripts in the StarterPack, and when I run the game, the script doesn't work, even though there are no output errors. Here's the code:

local player = script.Parent.Parent
function changed(prop)
	if (prop == "TeamColor") then
		if player.TeamColor == BrickColor.new("Bright blue") then
		local p = player.Character; 
		-- the ifs
		if p:FindFirstChild("Shirt") then -- same as ~= nil
			p.Shirt:Destroy()
		end
		if p:FindFirstChild("Pants") then
			p.Pants:Destroy()
		end

		-- adding the shirt & pants
		a = Instance.new("Shirt")
		a.ShirtTemplate = ("http://www.roblox.com/asset/?id=13997673")
		a.Parent = p

		b = Instance.new("Pants")
		b.PantsTemplate = ("http://www.roblox.com/asset/?id=31728834")
		b.Parent = p
		end
	end
end

player.Changed:connect(changed)
