         <span class="textfieldRequiredMsg">E-mail is required.</span><span class="textfieldInvalidFormatMsg">Opse! your E-mail is wrong.</span></span></div>

         <div id="contactbttn">
           <input name="sender" type="submit" value="click to send your message" />
         </div><!-- End ContactBttn -->

    </div><!-- End QuoteTopRight-->


    </div><!-- End QuoteTop -->

           <input type="hidden" name="recipient" value="info@siteripe.com" />
    <input type="hidden" name="redirect" value="yourURL/Thankspage" />

    </form>

you can save the name value into a cookie before form is submitted (using javascript), and then fetch it from the cookie using javascript.

http://www.quirksmode.org/js/cookies.html

or use a server side language (php etc)

---

If you want a cheap javascript version (no server-side code), you can do something like the following:

1. On submit of the form, append ?name={name here} to redirect variable.
2. On thanks.html, read the querystring variable and put on screen to user.

As adviced I used a PHP Form mailer, killed the line of Code that re-directs and then used

<?php echo $_POST["name"]; ?>,

to collect and display the name of the visitor on the thank you page
