Adding a Settings Field to my WP Sub Menu Page - php

Question

Hello I'm currently following a guide on how to add input to my created Sub Menu Pages. Here is a pic of what is showing up. http://imgur.com/a/St9wj .When I view the sub-menu page. No Errors, just not showing the text field. The Function function mytheme_general_name() is not getting called in the 2nd add_submenu_page, but I don't see what is wrong with it.
I copied the Here is my Current two php files in use
File Name: function-admin.php
/*
#package Jeron
========================
ADMIN PAGE
========================
*/
function mytheme_add_theme_options() {
// Generate Theme Options Page
add_menu_page('My Themes Theme Options', 'Theme Options', 'manage_options', 'theme2_options', 'mytheme_create_page', get_template_directory_uri().'/img/themeoptionsicon.png', 110);
// Generate Theme Options Sub Pages
