pngfix script not working

[tryin_to_learn]

I'm having a problem with this site in that the png transparencies aren't working in IE 6 or 7. I added a JavaScript file that I've used before to fix it but it's not working here. I may not be calling it correctly or something. The file is pngfix.js and I'm calling it in the header like this:

<!--[if lt IE 7]>
<script defer type="text/javascript" src="pngfix.js"></script>
<![endif]-->

Any ideas what I'm doing wrong and how to fix it? One thing that's weird about this to me is that before when I've used png files, they've worked in IE7 and this one doesn't. Also, the way I'm calling the script doesn't make sense if it's not working in IE7, either. Anyway . . . help?

That code is just a comment as far as IE7 is concerned as it is an instruction for only IE5 through IE6 to include the JavaScript.

IE7 supports PNG alpha channels you do not need a script for it.

Are you using a standalone version of IE (any version)?
