If you have written your payment page in PHP and want to stop people from viewing your source code and going straight to your return URL, there is a solution! We have created software that encrypts your PHP pages/scripts AND the HTML output GENERATED by your PHP scripts. This means, you could have: <? echo"<input type=\"hidden\" name=\"notify_url\" value=\"$my page\">"; ?> and our software will turn it into: sv*4Mrxivrix*4I|tpsviv*G*4nywx*4ks*4xs*4!Gf! (as example) but your page will run perfectly! For more of a demo on encrypting your pages, have a look at: http://www.websitecreati...elock/demo-encryptor.php Vince
