# Error when changing option name

 * I used the code as shown on [ Otto’s tutorial ](http://ottopress.com/2009/wordpress-settings-api-tutorial/)
   and tried to change the option name ‘text_string’ to something else – ‘embedded_url’.
   I have WP_DEBUG enabled. When I loaded my plugin’s settings page, right above
   my text input field is this error: “Notice: Undefined index: embedded_url in ….”
   and then it points to the echo line of this function:
 *     ```
       function plugin_setting_url() {
       	$options = get_option('plugin_options');
       	echo "<input id='plugin_url' name='plugin_options[embedded_url]' size='40' type='text' value='{$options['embedded_url']}' />";
       }
       ```
   
 * Since this is the only place that ‘text_string’ appears other than the validation
   method, I do not understand why ’embedded_url’ is not defined in the same manner
   as ‘text_string’ was. What am I doing incorrectly?
