Hi Melissa, unfortunately with PDF's it doesn't really work that way. Your best bet is to just link to the PDF. Click 'File Attachment' on the Add a New... menu and upload it as a menu item on your indexbar, or upload it in a page and link to it there. Chrome should load the PDF inline for the user so they can browse it and click the links.
If the PDF isn't too complicated, you could consider copying and pasting its contents into your website on a page instead?
Please let me know if you need any more assistance. You can also email me directly if you prefer.
All the best :)
