Why isn't my main story image popping up in its own Javascript defined window?

I'm using this Mason component (Perl embedded in HTML) to create our local news story pages.  If you notice starting at line 150 and going through line 170, I have specified a Javascript pop-up window when the main image is clicked upon to open our video player.  However after messing around with other elements in it this morning, clicking on the 'main image' no longer pops open the specified JS window but instead goes directly to the video url.  If you click the text caption and the 'play video' button below the main image, it still works correctly.  What did I forget or delete that disabled my pop up script on the main image?

story page example: http://treebeard.grokthis.net:8030/news/stories/8964359.html

here's the code:
