While Loop

Hi,

I have the following within some PHP code:

	   // run the while loop that grabs all the sidebar links for this type
	   while($r=mysql_fetch_array($readingresult)) { 
		  
		  $id=$r["id"];
		  $lurl=$r["lurl"];
		  $ltext=$r["ltext"];
		  $ldesc=$r["ldesc"];
		 
		 // make the link for this row
		 echo "<li><a href='$lurl' target='_blank' title='Click to open link in new window'>$ltext</a> - $ldesc <strong>[<a href='deletelink.php?cmd=delete&id=$id&ltext=$ltext'>Delete</a>]</strong></li>";
		}

it works fine but I would like to know how I could do a “No Link of this type” message instead of it just appearing blank when there are no result from the $readingresult query.
