Speakers custom fields

I think I'm missing the custom fields that create the "Facebook" and "Website" links like is shown on the example. All the custom fields I have to choose from are:
gavern-post-desc
gavern-post-keywords
gavern-post-params-aside
gavern-post-params-image
gavern-post-params-templates
gavern-post-params-title

and none of them does the trick. Am I missing something here?

Hi,

Did you check these fields for Speakers (not posts)? You can easily create a new Custom filed, just type name "Facebook" and value: <a href="http://facebook.com" rel="nofollow">http://facebook.com</a>

Didn't get that... Thanks for the help
