there is a donate form on my web-site. After clicking on donate button(form submit) it redirects to the external PayPal payment confirmation page. Is it possible, to embed(not with iframe or popup) this confirmation into my web-site? I don't want my customers to be redirected. For ex, after clicking on submit button, person is to be redirected to another page ON MY WEB SITE, where he can approve his payment. Thanks for any response!

Hope this was helpful
