I think robbingtime should be a global variable ? Try

pawn Код:

new robbingtime[MAX_PLAYERS];
forward RobberyBar(playerid);
public RobberyBar(playerid)
{
    robbingtime[playerid] ++;
    SetProgressBarValue(MyRobberyBar, robbingtime[playerid]);
    if(robbingtime == 15)
    {
        KillTimer(RobbingTime);
        HideProgressBarForPlayer(playerid,MyRobberyBar);
        HideProgressBarForPlayer(playerid,MyRobberyBar);
        robbingtime[playerid] = 0;
    }
    return 1;
}
