Opening iframe based on href selector.

I want to open a pop up based on the url in the link.
I added the following code to “Other Calls” tab. I’ve tested the syntax elsewhere and it appears to be correct. Any suggestions as to why this might not work.

jQuery("a[href='https://www.everytrail.com/view_trip.php?trip_id=2027383']").fancybox({
  'transitionIn': 'elastic',
  'transitionOut': 'elastic',
  'speedIn': 600,
  'speedOut': 200,
  'type': 'iframe',
  'height': 800
});

Thanks.
