Insert PDF in a link block?

Hi SI Team

Can I insert a pdf in a link block in a blog post?

This is not working for me!

This is the pdf that I am trying to insert:

http://www.spherico.com/filmtools/TitleExchange/XTE/XTE%20Help.pdf

Using the instructions here:

http://stackideas.com/docs/easyblog/administrators/composing/link-block

I am attempting to do so here:

http://finalbug.net/blog/entry/547-fcp-x-subtitles-the-missing-manual-part-02

(This last link is Currently only viewable as an admin)

I attempt to insert the pdf link and nothing happens.

best

Paul
