you need to define a condition

Код:

new string[128];
        new pName[24];
        if(isnull(params)) return SendClientMessage(playerid, -1, "{FF0099}[ADMIN]{FFFFFF} /unban [playername]");
        if(//File present)//like this
        {
            format(string, 128, "{FF0099}[ADMIN]{FFFFFF} '%s' has been unbanned by %s.", params,pName);
            SendClientMessageToAll(COLOR_ADMIN,string);
