You're missing a ] after url and a [ before /url.
Or you can do what I do and highlight the text u want to be the link, and click on the little chain icon that says Insert/Edit Link, then put your site address into the box and click "insert."
Example:
I want to put the story here (the word "here" being my clickable link).
I highlight "here" in the above sentence and click on the unbroken chain icon.
Then, in the box next to "Link URL" I would type the address that takes you to the story, in this case:
http://www.l5r.com/story/the-heavens%E2%80%99-command
After you type it in, click "insert" and you're left with a working link... one that will take you to where you want to go; in this case...

Edit: For the "Insert/Edit Link" button to even be an option, you must have text highlighted. If you don't you won't even have the option to click it.
When you cannot be deceived by men you will have realized the wisdom of strategy.
