I saw some of the solutions, but after the amendments still can not be resolved error.

PHP Code:

public OnMainConVarChange(Handle:convar, const String:oldValue[], const String:newValue[])
{
    SetConVarInt(h_BotJoinAfterPlayer, 0, true);
    SetConVarInt(h_BotDeferToHuman, 1, true);
    SetConVarString(h_BotChatter, "off");
    SetConVarInt(h_HudHintSound, 0, true);
} 


game.inc

PHP Code:

    SetConVarInt(h_BotJoinAfterPlayer, 0, true);
    SetConVarInt(h_BotDeferToHuman, 1, true);
    SetConVarString(h_BotChatter, "off");
    SetConVarInt(h_HudHintSound, 0, true);

I removed the ''true''，And find the code

PHP Code:

    h_BotJoinAfterPlayer = FindConVar("bot_join_after_player");
    h_BotDeferToHuman = FindConVar("bot_defer_to_human");
    h_BotChatter = FindConVar("bot_chatter");
    h_HudHintSound = FindConVar("cl_hudhint_sound"); 


I think this place should be out of the question，What should I do?
