How would I make this script loop, and why isn't the kill function working?

This script will run once, but the kill function

end
end
for i, player in pairs(game.Players:GetPlayers()) do
player:BreakJoints()
end
end

Won't work. How would I make the whole script loop, and what's the error with the kill function?

time=0
while true do
wait()
time=time+30
for i=1, 30 do
    time=time-1
    wait(1)
    for i, player in pairs(game.Players:GetPlayers()) do
    player.PlayerGui.TimerSet.Frame.Time.Text=tostring(time) 
end
end

time=time+45
for i=1, 45 do
    time=time-1
    wait(1)
    for i, player in pairs(game.Players:GetPlayers()) do
    player.PlayerGui.TimerSet.Frame.Time.Text=tostring(time)
end
end
for i, player in pairs(game.Players:GetPlayers()) do
player:BreakJoints()
end
end

Whole script Thanks!

You can't break joints of a Player, but of its character. Just change to this:

for i, player in pairs(game.Players:GetPlayers()) do
	player.Character:BreakJoints()
end
