thank you and redirect page

After the user clicks the submit button to make a payment, how can I ensure that:

1 - after they make a payment they see a 'thank you' page and then...

2 - are redirected to the form again  

Hi,

It is only possible to redirect them once.  You could direct them to a thank you page with a link back to the form or you could redirect them back to the form itself but not to a thank you page:

A single automated redirect is all that is possible though.  So you would need to choose whether they are directed to the thank you page or to the form itself.
