Embedded video invisible after text wraparound

I am using the div tags and so on to make a video justify to the left while text wraps around it. This works fine, except the video is not showing up. The text is wrapping around a big white block.

Code is below…

<div style="float:left;margin:0 10px 5px 0;"><object width="430"
height="248"><param name="movie" value="http://www.youtube.com/embed
/zQR1l_M7q9Q"></param><param name="allowFullScreen" value="true">
</param><param name="allowscriptaccess" value="always"></param><embed
src="http://www.youtube.com/embed/zQR1l_M7q9Q" type="application/x-
shockwave-flash" allowscriptaccess="always" allowfullscreen="true"
width="320" height="265"></embed></object></div>
