JavaScript (jQuery)

function display_youtube(new_url) {
    $('#movie_url').removeAttr('value');
    $('#embed_url').removeAttr('src');
    $(document).ready(function() {
        $('#movie_url').attr('value', new_url);

HTML

<object width="720" height="480">
<param id="movie_url" name="movie" value="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" />
<param name="allowFullScreen" value="true" />
<param name="allowscriptaccess" value="always" />
<embed id="embed_url" src="http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=0" type="application/x-shockwave-flash" allowscriptaccess="always" allowfullscreen="true" width="720" height="480" />
</object>

Hyperlink

<a href="javascript:display_youtube('http://www.youtube.com/v/_eaToCSn7yU?f=user_uploads&app=youtube_gdata&autoplay=1');">Click Here for Fun!</a>

What I've done is parsed YouTube's API for the videos on my user channel. The hyperlink above is php generated, meant to trigger the above JavaScript function, and swap the url from attributes contained in ids "movie_url" and "embed_url". Works just like it should in FF, but IE will only perform the .css commands. My guess? IE doesn't like me assigning IDs to PARAM and EMBED, perhaps? What do you think?
