How do I fix this issue where I try to check the amount of winners and it throws an error?

Hi, I have an issue where I try to check the amount of winners using a table and Teams and it for some reason throws this error, "ServerScriptService.ServerHandler:148: attempt to get length of a nil value"

I have tried to fix this buy making an elseif statement that checks if #Winners is false or nil, and it doesn't work. This is where the issue is:

local Bomb = game.ServerStorage.Bomb
local Coin = game.ServerStorage.Coin
local intermission = 30
local gameTime = 60

    local LosingHorn = game.Workspace.Music.LosingHorn

    IntermissionMusic.Playing = true
    --Intermission

    repeat
        intermission = intermission - 1
        wait(1)
        bannerTextValue.Value = "Intermission: ".. intermission 
    until intermission == 0 

    IntermissionMusic.Playing = false
    --Game starts
    if intermission == 0 then
