Hello!
I was trying to chek last player's login with a command.
I get : (25429) : error 035: argument type mismatch (argument 1)

PHP код:

CMD:online(playerid, params[])
{
    new str[28],path[50],pLastOn[ 20 + 20 ],OnlineString[ 128 ],INI:file;
    if(sscanf(params,"s[30]",str)) return SendClientMessage(playerid,-1,"Usage: /online [name]");
    format(path,sizeof(path),"Accounts/%s.ini",str);
    if ( INI_Exist( path ) )
    {
        file = INI_Open(path);
        GetPVarString( str, "On", pLastOn, sizeof pLastOn );//25429
        format( OnlineString,sizeof(OnlineString),"["REDSV"%s"BLUESV"] last Online time is "REDSV"%s.",str,pLastOn);
        SCM(playerid,BLUES,OnlineString);
        INI_Close(file);
    }
    else
    {
        SendClientMessage(playerid,-1,"User in not registered.");
    }
    return 1;
}
