[SOLVED] How to forward to another web page

After the entire checkout process is complete and payment has been confirmed how do I have HikaShop rfoward the user to a new wab page?

I would like the
"Your order is now complete.
The amount of $25.00 will be collected upon delivery of your order (D3)
Thank you for your purchase."

to appear and then after a certain period of time the form needs to foward to another page in the site.

You can go in the menu Display->Views. There, edit the file end of the view checkout. There, you can add some javascript to redirect after some time.
For example, the code:
<script type="text/javascript">
setTimeout( "window.location='http://www.my_website.com/my_redirect_page.html'", 5000 );
</script>

will redirect your user to the URL http://www.my_website.com/my_redirect_page.html after 5 seconds.
