file exist check failing

[eluser]bhakti.thakkar[/eluser]
hello,
its via HTTP

in config.php i have defined Uploadfiles_url as
$config['UploadFiles_url'] = "http://IP_ADDRESS/UPLOADFOLDER/";


<?
foreach($query->result() as $row):
$source=$this->config->item('UploadFiles_url')."PDF_files/";

?>
<td><a >AttachedFile_VC?&gt;" target="_blank">&lt;?=$row->AttachedFile_VC;?&gt; </a></td>

Hope its clear

* [href="&lt;?=$source.$row->AttachedFile_VC" ]


and many files do get opened by the above method. but i dont want to display page not found error for those files which now do not reside on the specified path any more

Thanks
