I have some problems with jfeed

Question

I'm trying to use Jfeed to parse an rss feed. This line of code inside the jfeed file does not work

    this.link = jQuery(channel).find('link:first').text();

however this other line works

     this.title = jQuery(channel).find('title:first').text();

I noticed that every line of code which tries to retrieve a link or description from my rss feed does not work. Can anybody deduce what the problem is?

Below is a snapshot of the rss feed
