        while($myrow = mysql_fetch_assoc($result))
             {
                     echo "<b>";
					 echo "<h2>";
                     echo $myrow['title'];
                     echo "</h2>";
					 echo "</b><br><i> Julkaistu:";
                     echo date("d.m.Y",strtotime($myrow['dtime']));
                     echo "</i><hr>";
                    
			   echo stripslashes(nl2br($myrow['text1']));
                     echo " ";
					 echo "<br><br>";
					 // tästä alkaa linkin piilotus
					 $kysely = "SELECT name FROM uutiset_tiedostot
		 WHERE newsid='$newsid' ";
		
		  $linkki = $dbLink->query($kysely);
		  
	
                // Make sure the result is valid
                if($linkki->num_rows == 1) {
		
					
					 echo "<br><br><a href='avaa_tiedosto.php?id={$myrow['newsid']}'>{$myrow['name']}</a>";
                    
                     echo "<br><br><a href=\"javascript:self.history.back();\"><-- Takaisin</a>";
             }
			 
			 
			 else {
