当我将谷歌地图添加到我的网站时，该页面不会显示在IE7中

Question

我在这里有http://hearingaidneeds.com/?page_id=8这个网站，如果你在IE7中查看它，页面就不会显示。这是我的代码......

<div class="contentText">

    <div style="float:right; width:425px;">
<iframe width="425" height="350" frameborder="0" scrolling="no" marginheight="0" marginwidth="0" src="http://maps.google.ca/maps?f=q&amp;source=s_q&amp;hl=en&amp;geocode=&amp;q=672+Brant+Street,+Burlington,+ON&amp;aq=0&amp;oq=672+Brant+Street&amp;sll=43.447946,-79.624382&amp;sspn=0.456129,0.876846&amp;ie=UTF8&amp;hq=&amp;hnear=672+Brant+St,+Burlington,+Ontario+L7R+2G6&amp;t=m&amp;z=14&amp;ll=43.338828,-79.805332&amp;output=embed"></iframe><br /><small><a href="http://maps.google.ca/maps?f=q&amp;source=embed&amp;hl=en&amp;geocode=&amp;q=672+Brant+Street,+Burlington,+ON&amp;aq=0&amp;oq=672+Brant+Street&amp;sll=43.447946,-79.624382&amp;sspn=0.456129,0.876846&amp;ie=UTF8&amp;hq=&amp;hnear=672+Brant+St,+Burlington,+Ontario+L7R+2G6&amp;t=m&amp;z=14&amp;ll=43.338828,-79.805332" style="color:#0000FF;text-align:left">View Larger Map</a></small>

</div>

contentText内的所有内容都没有显示......代码在那里，但没有任何内容显示。

如果我删除了iframe页面，并且它在每个浏览器中看起来都很好，但不是IE7，我做错了什么以及如何解决？

谢谢， Ĵ
