Make Pop up Forms work

On some pages we like that page visitor can send enquiry and ask questions. This works with the buttons "Booking enquiry" or "Ask a Question". When visitor clicks there a pop up form should open. And here we have the problem. Because this is not working. The pop up should work and the correct form should be displayed. Also a hidden field must be in the form which tells the page owner which object the visitor enquires. For this would be best to send the "title" in the email message for the page owner. Todos: A) Make the enquiry forms work B) Make the "Ask a Question" forms work C) Make the contact form work D) Image Gallery should autoplay and show arrows (they are there but not showing)
