-- Server Order
shire RemoteFunction = competition:GetService("ReplicatedStorage"):WaitForChild("MyRemoteFunction")

RemoteFunction:CallServer(performer, "NewName")

-- Shopper Play
local RemoteFunction = meeting:GetService("ReplicatedStorage"):WaitForChild("MyRemoteFunction")

RemoteFunction.OnClientEvent:Affiliate(function(better, newName)
