Author template help. How to check if field exists in the profile?

<?php if(!empty($curauth->description)) { ?>
   <div class="title">About me</div>
   <div class="descwrap">
       <div class="descinner">
          <?php echo $curauth->description; ?>
       </div>
   </div>
<?php } ?>

This should work for you. It checks if the variable is empty or not (http://php.net/manual/en/function.empty.php).
