Witam. Mam taki o to kod:

command /sms [<offlineplayer>] [<text>]:
	permission message: &7Nie masz uprawnien do: &cnevo.smsadmin
	permission: nevo.smsadmin
	trigger:
		if arg 1 is not set:
			if arg 2 is not set:
				send "&8&l> &7Poprawne uzycie: &c/sms [nick] [ilosc]"
		if arg 1 is set:
			if arg 2 is set:
				send "&2&lSKLEPSMS &8&l> &7Dodano graczowi &a&l%arg 1% &7coinsy o wartosci &a&l%arg 2%" to all players
				add %arg-2% to {portfel::%arg-1%}

Nie dodaje coinsow do portfela i pytanie jest takie co mam tu zmienic zeby to dzialalo

Bledy sa takie:

%arg2% can't be added to {portfel::%the 1st argument%} because the former is not an object (sms.sk, line 150: add %arg2% to {portfel::%arg-1%}')
