You would do far better not to rely on javascript for this at all. Instead you should parse the post with PHP and from that display a confirmation for the delete if delete was selected. That is...

Try this:

<!--[if !IE]> -->
<object type="application/x-shockwave-flash"
data="http://www.zeriislam.com/menu.swf" width="923" height="90">
<!-- <![endif]-->
<!--[if IE]>
<object...

Usually the simplest thing to do is to click on the yellow ! icon in the bottom left of the browser window in IE. This will tell you the error. Better still, use Firefox and use the error console....
