You've got the right idea, but the variable that holds the link (made by "linkify") is not named "a".

Also, appending it to h2 would make it a child of the heading, but it should be a sibling of the heading and share the div as a parent.

Its not working, Can U please specify a bit .???

On your "appendChild" line:

  • where you have "h2", what can you put to refer to the parent (div) element instead?
  • then instead of "a", what argument can you give that will identify the link previously made by calling "linkify"?

If it's still not working after you make these changes, show what you have now.
