 <p>Fire up firebug and see if you're actually getting Javascript sent down the wire. Is there a 404 or 500 whooshing by? Or is code loading correctly? Is your event handler being called? Add a <code>console.log</code> or <code>alert</code> to your handler to test. Is your handler even being attached? Did you put the whole thing in a <code>$(document).ready()</code>? Did you put your script after the <code>jquery.js</code> file, so that jQuery is available when your script attaches event handlers? In general, you know, do that debugging thing we all love so much.</p>
