Undefined variables term and fields_tag

did not comment the code

looking at the api for drupal 7 terms is not there. but it is there in drupal 6.

http://api.drupal.org/api/drupal/modules!node!node.tpl.php/7

i changed the code to this. i replaced the $terms with render($content['field_tags'])). it seems to have gotten rid of the problem but i do not think it is working.

   <?php if ($submitted || render($content['field_tags'])): ?> 
	<div class="submitted">  
	<?php if ($submitted): ?>
	<?php print $date?> by <?php print $name ?> 
	<?php endif; ?>
	&nbsp; 
	<?php if (render($content['field_tags'])): ?>
	<?php print '<div class="taxonomy"> ' . render($content['field_tags']) . '</div>'; ?>
	<?php endif; ?>
	 </div>
<?php endif; ?> 

followed this mans output

i checked the value of the content array but it does not seem to contain field_tags value.
