Trying to put all players on a team into a different one. but no error?

there are no errors at all to tell me what is wrong. I don't know what to do.

local Spectators = game:GetService("Teams").Spectating:GetPlayers()
while true do
    wait(5)
    print("Checking")
    for i = 1, #Spectators do
        Spectators[i].TeamColor = game:GetService("Teams").MTF.TeamColor
        Spectators[i]:LoadCharacter()
        print(#Spectators)
    end
    wait(150)
    for i = 1, #Spectators do
        Spectators[i].TeamColor = game:GetService("Teams").Chaos.TeamColor
        Spectators[i]:LoadCharacter()
        print(#Spectators)
    end
end
