What can be added to the tpCars function?[Unsolved]

What can I add to the function to have the system count how many players there are and have that implement to the amount of gokarts set up. I have a feeling also, that one of my scripts might error since I made the dictionary to fit 15 cars but won't recognize them do to no Go kart# for not being there due to amount of players. I have the gameSpawns set up, I just need the amount of cars to spawn with the amount of players. Some how the system needs to count how many children of Players and implement with the cars in the storage which are named GoKart1, GoKart2, GoKart3, etc Tis is my goal for today and I couldnt figure it out

teleportGame = game.ServerScriptService.teleportGame
teleportLobby = game.ServerScriptService.teleportLobby



function enableTPgame()
wait(3)
teleportGame.Disabled = false
end


function disableTPgame()
wait(3)
teleportGame.Disabled = true
end

function tpCars() --tpcar function

end


enableTPgame()

wait(10)
tpCars()   --where car tp function will be
wait(10)

disableTPgame()

wait(1)

enableTPgame()
