event.preventDefault() doesn't work in my browsers?

Hi there, I hope someone can help me. I have this code:

$("#imageGallery a").click(function(event){
  event.preventDefault();
  var href = $(this).attr("href");
  //1.1 Show the overlay
  //1.2 Update overlay with the image linked in link
  //1.3 Get child's alt attribute and set caption
});

And I know it SHOULD work because I passed the Challenge, but I don't understand , Firefox and Chrome both still use the a href link as default and go through to the image.

I've installed a Jquery plugin for Firefox but still no luck...

HI Tawny Bartlett

Have you checked the JavaScript console for any syntax errors? In Chrome you can open the JavaScript console with Ctrl-Shift-J (windows) or Cmd-Option-J (Macs). Open the console and reload the page -- do you see any errors listed? A syntax error will prevent your programming from running, so the preventDefault() method won't work either.

Hmm... It's working now... I have no idea what happened unfortunately, I can't see any errors or warnings now! I did the next step in the project and it's suddenly started working?!

Hmm.. thank you for the advice though, I will look for errors and warnings next time. :)
