Dynamic PDF download

Hi,

We are using Marketo form embed code and put it in drupal site(http://www.attuneww.com)

We have a Book Download form on our site. This form is on all Books pages.(Same Form).
When a visitor submits this form from a book publication page, a book download link for that Book should be send to that visitor through email.

So how can we do this in Marketo?

We have created simple form in Marketo for Book Download.

Regards,
Sahejin
