Ask for details prior to downloading content

Hello, I am using the Zoho CRM Integrator on a site and it is doing what it is supposed to, and asking for details when particular pages or loaded, or when someone reaches a particular point in the page (ie. once they get to a particular anchor, details are asked for).

Is it possible currently to have the plugin ask for details purely when a user clicks on some downloadable content, such as a Word document?

So ideally, the user can browse around the page as much as they like, and when they click on the the link for the document they are then prompted to enter their details. Can this be done?

Thanks in advance
