How do I add my Facebook profile link to tumblr?

[Jesse]

Hi there, all my friends that have tumblr have there Facebook profile link in the description box so there followers can add then on Facebook. I am also wanting my Facebook profile link on my tumblr blog but whenever I add the link to my description box and save it i go to click on the link and it says


". This content is currently unavailable
The page you requested cannot be displayed right now. It may be temporarily unavailable, the link you clicked on may have expired, or you may not have permission to view this page."

Why does it always do this whenever someone clicks on the link? I am only 16 so could it have something to do with my Facebook security settings? and if so is there a way to change them. all my friends are 16, 17, and 18 and they have no problem with it. can someone please help me!!!!!
