You need to update the main thread instead of posting the update in the comment section.
Also, if you wish to expand the usage of the plugin, maybe implementing a check see if there are args behind the command. Like
PHP Code:
public Action:CmdBots(client, args)
{
if (args != 1)
{
ShowBotMenu(client);
return Plugin_Handled;
}
decl String:arg[16];
GetCmdArg(1, arg, sizeof(arg));
/* tf_bot_add <arg here>..... */
return Plugin_Handled;
}
