I am not a great web developer but from my experience what I would suggest in a scenario like this is reducing the code to the absolute minimum. In this case - you don't need all these parameters. What is enough to display a banner is this:
<object width="468" height="60">
<param name="movie" value="lop.swf?clicktag= http://www.adobe.com" />
<embed src="lop.swf?clicktag= http://www.adobe.com" width="468" height="60"/>
</object>
Also now as I wrote it, I noticed that you are missing the "<embed>" tag in your code. That reason alone is the cause for the banner not showing. So maybe first you can try just adding this line:
<embed src="lop.swf?clicktag= http://www.adobe.com" width="468" height="60"/>
Right after this line:
<param name="swfversion" value="6.0.65.0" />
And if that doesn't help, just try doing what I suggested in the first place. Tell me how it went :)
