Linking wp.org to Feed Burner using widget in sidebar.

Hello Everyone,

What widget do you suggest I drag into the sidebar of a theme (Appearance – Widgets) to link a wp.org side to Feed Burner.

Are there steps or tips on how to make sure a Feedbuner feed” is “on” or “found”?

Backstory:

After much reading about what an RSS is and what a “feed” is I signed up for a Google/ feed Burner account. I dragged a widget into the Sidebar and now visitors to my site can click on my feed. However, clicking that results in the message “feed not found” and “there must be a problem with the feed.”

Thank you.
