Sending information to server?

So in my shop gui I want to have only 1 function that fire every time I click any of the purchase buttons. In the purchase button script it will check its parent's name and send that to the server but I don't actually know how to do this

I tried doing this but obviously it doesn't work.

In the purchase localscript:

script.Parent.MouseButton1Down:Connect(function()
	local Price = 20
	game.ReplicatedStorage.PurchaseApple:FireServer(Price)
end)

In the ServerScriptService

game.ReplicatedStorage.PurchaseApple.OnServerEvent:Connect(function(Price)
	print(Price)
end)

Instead it just prints the playername
