eBay 125px Banner Ad

I need help. I added eBay 125px X 125px banner code to my Ad Squares widget but since I added the java banner code, it has both been squeezing and resizing my site logo even though it is not even on that section of the site. My logo is on the header section and the eBay 125px X 125px code is in the side bar.

Here is the eBay banner code
[<script language=’JavaScript1.1′>
document.write(“<sc”+”ript language=’JavaScript1.1′ src=’http://rover.ebay.com/ar/1/711-53200-19255-200/1?campid=5337381171&toolid=7115320019255200&customid=Right+Side+Bar+125+Ad&mpt=&#8221; + Math.floor(Math.random()*999999999999) + “&adtype=3&size=125×125&mpvc=’></sc”+”ript>”);
</script>
<noscript>

<img border=’0px’ src=’http://rover.ebay.com/ar/1/711-53200-19255-200/1?campid=5337381171&toolid=7115320019255200&customid=Right+Side+Bar+125+Ad&mpt=%5BCACHEBUSTER%5D&adtype=1&size=125×125&mpvc=&#8217; alt=’Click Here’>
