help please... session -> database

hello, i have hit a major stumbling block and am now getting really frustrated.. if someone could point me in the right direction i would really appreciate it.. - i have a set of forms across a number of pages - the user enters data into each of the forms and these are placed in a session variable - at the completion of form entry the session variables are supposed to be passed to a mysql database - one of the variables is a URL for some reason the form entry the data is encoded so that a full stop '.' is changed into an AT '@' - I have tried urlencoding and decoding the session, using str_replace for the @ .. adding slashes - for some reason this just wont work .. ... help? ... i.e Adds form post to session if (is_array($HTTP_POST_VARS)) {

     while (list($var, $value) = each($HTTP_POST_VARS)) {
     session_register($var);
     $HTTP_SESSION_VARS[$var]=$value;

     }
    }

i.e adds session to database (simplified so as to find problem) $title =stripslashes($HTTP_SESSION_VARS["title"]); $href= $HTTP_SESSION_VARS["HREF"]; $fee =stripslashes($HTTP_SESSION_VARS["fee"]); $result= mysql_query("INSERT INTO links (Title, Hyperlink,fee) VALUES ('$title','$href','$fee')") or die(mysql_error());

                              print $result;
