minusowy czas, pomocy :c

Witam, napisalem skrypt na timer, i wszystko ladnie dziala. Ale gdy jest czas 0:00, to czas leci dalej i jest na minusie...

every 1 second:
	loop all players:
		if {odliczanie.%loop-player%} is true:
			if {chat.%loop-player%} is false:
				remove 1 from {sekundy.%loop-player%}
				if {sekundy.%loop-player%} is 0:
					set {sekundy.%loop-player%} to 60
					remove 1 from {minuty.%loop-player%}
					if {minuty.%loop-player%} is 1:
						if {sekundy.%loop-player%} is 0:
							set {minuty.%loop-player%} to 0
							set {sekundy.%loop-player%} to 59
							remove 1 from {sekundy.%loop-player%}
							if {sekundy.%loop-player%} is 1:
								if {minuty.%loop-player%} is 0:
									set {sekundy.%loop-player%} to 0
									set {chat.%loop-player%} to true
									set {odliczanie.%loop-player%} to false
									send "&aTwoj chat zostal odblokowany !" to loop-player
									clear {sekundy.%loop-player%}
									clear {minuty.%loop-player%}
									stop
