Why won't my Touch part +100 USD<-- Points script work?

Im trying to make a script that if you touch it, it will give you +100 for each time you touch

part = script.Parent
game.Players.PlayerAdded:Connect(function(plr)
	print(plr.Name)
	part.Touched:Connect(function()
	leaderstats = plr:FindFirstChild('leaderstats')
	if leaderstats then
		Yuan = plr:FindFirstChild('Yuan')
		if Yuan then
			Yuan.Value = Yuan.Value + 100
		end
	end
end)
	
end)

LeaderBoard script

datstore = game:GetService("DataStoreService")
local datast1 = datstore:GetDataStore("Yuan")
local datast2 = datstore:GetDataStore("USD")

game.Players.PlayerAdded:Connect(function(plr)
	local folder = Instance.new("Folder",plr)
	folder.Name = "leaderstats"
	local Yuan = Instance.new("IntValue",folder)
	Yuan.Name = "Yuan"
	local USD = Instance.new("IntValue",folder)
	USD.Name = "USD"
Yuan.Value = datast1:GetAsync(plr.UserId) or 0
datast1:SetAsync(plr.UserId, Yuan.Value)

USD.Value = datast2:GetAsync(plr.UserId) or 0
datast2:SetAsync(plr.UserId, USD.Value)

Yuan.Changed:Connect(function()
	datast1:SetAsync(plr.UserId, Yuan.Value)
end)
USD.Changed:Connect(function()
	datast2:SetAsync(plr.UserId, USD.Value)
end)
	
end)
