My Script is here:

 <?php
                        if($_POST['updatesitesettings'])
                            {

                             $target = $target . basename($_FILES['profile']['name']); 
                             $ok=1; 
                             move_uploaded_file($_FILES['profile']['tmp_name'], $target);
                             if($target == "stored/")
                             {
                             $target = "Attachment is Empty";                           
                             }

Retain how? There's no explanation with regard to what you want. Dumping 201 lines of markup and code won't help. Just include the relevant bits please, otherwise your post may get ignored. I sugegst you re-post with a cut down version of the above - 80% seems irrelevant to your issue - and explain clearly what you want and what's going wrong. Any errors?

i am not getting value of FileUpLoad after postback and when i edit the fields without selecting file upload.

even i have saved value in session also. but it is not getting value.
