--This is an event that happens when the round ends
game.ReplicatedStorage.GetWinners.OnClientEvent:Connect(function()

end)

I have this script I found from the Roblox Documentation. I want to utilize it in a voting system. What I’ve done is have this script be enabled once the round starts and if it’s been voted on. But nothing happens once the script is enabled. What’s wrong?

You’re using a global variable “script” in a script that has no such variable.
