将设置字段添加到WP子菜单页面

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
