I have this error that I keep getting and I have no idea why I'm getting it and I have no idea how to fix it.

PHP код:

Line (13643) : error 006: must be assigned to an array 


Here is the code:

PHP код:

COMMAND:referr(playerid, params[])
{
    new playername[24], string[100];
    if(!PlayerInfo[playerid][pReferedBy]) return SendClientMessage(playerid, COLOR_GRAD3, "You have already previously referred somebody.");
    if(sscanf(params, "s[24]", playername)) return Usage(playerid, "/referr [playername]");
    //Pull MySQL information from the SQL database
    format(string, sizeof(string), "SELECT `Name` FROM `users` WHERE `Name`='%s'", playername);
    mysql_query(string);
    mysql_store_result();
    if(!mysql_num_rows()) return SendClientMessage(playerid, COLOR_GRAD3, "The players name you provided is not an existing players name.");
    if(accountID[playerid] == GetOfflinePlayerInt(playername, "accountid")) return SendClientMessage(playerid, COLOR_GRAD3, "You cannot another one of your characters.");
    if(PlayerInfo[playerid][pIP] == GetOfflinePlayerInt(playername, "ip")) return SendClientMessage(playerid, COLOR_GRAD3, "You cannot referr somebody with the same IP Address.");
    mysql_free_result();
    //Referral system
    PlayerInfo[playerid][pReferedBy] = playername;
    return 1;
} 


The error is pointing to this line: PlayerInfo[playerid][pReferedBy] = playername;
