content type field not printing In drupal 7, I defined a field for a custom content type and am trying to display its value via page.tpl.php.  Nothing is appearing in the rendered page.

Here's the relevant piece of page.tpl.php.  The field is 'field_mast".  Note that I added print $title just so I could be sure that this template is being used.  It is.

    &lt;h1&gt;Perinote&amp;trade; &lt;?php print $content['field_mast'] ?&gt;&lt;br&gt;
       &lt;?php print $title ?&gt; &lt;br&gt;Organize Your Way&lt;/h1&gt;


My content type fields are:

Label  machine name field type            widget
Title  title        Node module element
mast   field_mast   Text                  Text field
Body   body         Long text and summary Text area with a summary


And for Manage Display, I have:

Field   Label        Format
Body    &lt;Hidden&gt;     Default
mast    Above        Default


Finally, for my actual content, I have:

Title: Notes contacts....
mast: User Guide
Body &lt;p&gt;This user guide...
Text format: Full HTML


Any ideas on what I need to do to get 'mast' to print?
try 

&lt;h1&gt;Perinote&amp;trade; &lt;?php print render($content['field_mast']); ?&gt;&lt;br&gt;


or this one 

&lt;h1&gt;Perinote&amp;trade; &lt;?php print render($content['field_mast']-&gt;value); ?&gt;&lt;br&gt;


I recommend you to download and install devel module and write

&lt;?php kpr ($content);?&gt;


to see what $content contains. you can also call this function in hook_preprocess_page as well.
