[Threshold]

The code above fixes the problem, you just need to change the name of the command.

The problem was here:

pawn Код:

if(PlayerInfo[playerid][JobContract] < 5) return SCMF(playerid,SVIJETLOPLAVA,"You can't quit, you are done %d hours of 5 job contract !",PlayerInfo[playerid][JobContract]);

If PlayerInfo[playerid][JobContract] == 0, then 0 is less than 5 (0 < 5). So you will get that error message.
So I made it:

pawn Код:

if(0 < PlayerInfo[playerid][JobContract] < 5)

If PlayerInfo[playerid][JobContract] is between 0 and 5, then send the message.
