How do you announce which team won the round after the game clock expires? [closed]

Hey, I am making a game and it has 5-minute rounds. The leaderboard tracks something called team kills which is basically the number of kills the entire team got combined. My goal is to make it so that when each round ends, the game will figure out which team has more team kills and announce in a screen GUI who won. I have scripted the clock, leaderboard, weapons, arena, GUIs, and everything else successfully I just need help with the determining who won the game, announcing it after every game, then restarting the round (resets all players). If someone could help me with this that would be really appreciated. Thanks for your time.

Pertinent Details: The two teams are called Red and Blue (This might change later on but those are the names for right now)

This is my working timer script (I do NOT need help with this script, it works, I just thought it might be needed to help with the requested script):

repeat while true do wait(1) if script.Parent.Value == 0 then local map = game.Workspace.LaserArena map:Clone().Parent = game.Workspace wait(5) game.Workspace.LaserArena:Destroy() wait(5) script.Parent.Value = 300 script.Parent.Value = script.Parent.Value -1 else script.Parent.Value = script.Parent.Value -1 end end until character == nil

Thank you, Skyraider5
