You almost have it. Your display is perfect but the links are dead.
when you click the

button, you'll notice the pop up box already has a http prefix in it. I think your link also had the http in it so you ended up with two of them and a bad address.
I'll fix the top one so you can what the format looks like
For the benefit of others reading....
If you want to have your link contain a custom description, edit the link as follows. Note I changed the first "url" to a "xrl" so it would display, you'd have the "url" in first postion.
