Custom text area with advanced editor doesn't save to db

Hi,
​
I have added a text area to a form with an advanced editor using the code below. I want to save the content of the text area to my db using a DBSave. It worked when I had a text area on the designer tab. But with the custom text area from below, DB save doesn't save the content in the database. The field of the corresponding table in the database is called RoadMap. What am I doing wrong?
​
Thanks!

<?php
$editor =JFactory::getEditor();
$params = array( "smilies"=> "0" ,
  "style"  => "1" ,  
  "layer"  => "0" , 
  "table"  => "0" ,
  "clear_entities"=>"0"
  );
echo $editor->display( "RoadMap", $form->data['RoadMap'], "400", "400", "20", "20", false);
?>

Does the generated HTML include a field NAME?

Also make sure the generated field is within the form tags

Hi,
​
Thanks for the answers. The question if the textarea was within the form-element solved it for me. I placed the custom html on the setup tab in Chronoforms. It should be on the design tab, than it is within the form element.

Thank you!
