Guys i need someone fix this problem ? when i compile that code i have this error:

 Error: IntelliSense: expression must have integral or enum type

i have problem in this part:

Console(0, V("seta sv_hostname " + servername + ";\n"));

so how i can fix that

if (strncmp(command, V("exec config_mp"), 14) == 0)
{
    if (GAME_MODE == 'D')
    {
        CIniReader iniReader(V(".\\teknogods.ini"));
        char *servername = iniReader.ReadString(V("Settings"),V("Servername"),"");

        if (strcmp(servername,"") == 0)
        {
            info("Server name set to defult.");
        }
        else
        {
            //Console(0, V("seta scr_teambalance 1;\n"));
            Console(0, V("seta sv_hostname " + servername + ";\n"));
            info("server name set to: %s.", servername);
        }
    }
