Can anybody help me with the following please? I get an error from this part of the script i'm using:

pawn Код:

stock IsNumeric(string[]) { for (new i = 0, j = strlen(string); i < j; i++) if (string[i] > '9' || string[i] < '0') return 0; return 1; }

stock ReturnPlayerID(name[]) {
    for(new i = 0; i < MAX_PLAYERS; i++) {
        if(strfind(PlayerName(i), name, true) != -1 || (IsPlayerConnected(i) && strval(name) == i && isNumeric(name))) {
            return i;
        }
    }
    return -1;
}

From this I get the following error:
