Making A Clicker Game And Have This I Cant Figure Out How To Make Work?

so im trying to make a clicker game where it saves the price of what your item is at but the datastore is too confusing for me ive looked on youtube but i dont understand it could someone please help also there are 2 scripts

this is the script thats for the item its a local script in a starter gui

button = game.StarterGui.Shop.Frame.ImageButton
player = game.Players.LocalPlayer
cost = game.ReplicatedStorage.StatFile.LocalPlayer.statnumbers.cost1.Value
add = 1

button.MouseButton1Down:connect(function()
	if player.leaderstats.Money.Value >= cost then
		player.leaderstats.Money.Value = player.leaderstats.Money.Value - cost
		player.leaderstats.MPS.Value = player.leaderstats.MPS.Value + add
		cost = cost + 50
	end
end)


while true do
	wait(0.01)
	script.Parent.Text = "Cost: "..cost
end

So you need an easy to understand and use DataStore script to save your leaderboard? Worry not, got just the right tool for you, saves automatically the values and names!

Just put this in a SCRIPT in Workspace

game.Players.PlayerRemoving:connect(function(player)
	local datastore = game:GetService("DataStoreService"):GetDataStore(player.Name.."Stats")--Player key

local statstorage = player:FindFirstChild("leaderstats"):GetChildren()
for i =  1, #statstorage do
	datastore:SetAsync(statstorage[i].Name, statstorage[i].Value)
	
end
end)


game.Players.PlayerAdded:connect(function(player)
		local datastore = game:GetService("DataStoreService"):GetDataStore(player.Name.."Stats")
	
	player:WaitForChild("leaderstats")
	wait(1)
	local stats = player:FindFirstChild("leaderstats"):GetChildren()
	for i = 1, #stats do			
	stats[i].Value = datastore:GetAsync(stats[i].Name)
		end
end)
