Adding Amazon search box widget in WordPress sidebar

I’m trying to add this amazon search box in my wordpress sidebar. I placed the code I was given in widget area but it’s not showing anything.
I think it’s because the code is javascript.
Anyone know how to sort out the problem?
Here is the code:

<SCRIPT charset=”utf-8″ type=”text/javascript” src=”https://ws.amazon.com/widgets/q?ServiceVersion=20070822&MarketPlace=US&ID=V20070822/US/croashop-20/8002/e8c9224a-735a-4783-8b52-9e3ccd140e36″&gt; </SCRIPT>
