Problem with 'spread the word' badge?

Question

I used the first (smaller vertical) badge at https://www.mozilla.org/en-US/plugincheck/ on my Wordpress blog but although it shows the badge, it also shows the second half of the HTML: "var pfsNextImage = "https://www<i></i>.mozilla<i></i>.org/img/covehead/plugincheck/wb/en-US/180_150/safe.png";var pfsUpdateImage = "https://www<i></i>.mozilla<i></i>.org/img/covehead/plugincheck/wb/en-US/180_150/upyourplug.png";"
If I remove that part, it just shows the badge, but do I lose anything but not including the part I've removed?
The whole code is:
<pre>&lt;a href="https://www<i></i>.mozilla<i></i>.org/en-US/plugincheck/"&gt;&lt;img id="mozilla_plugin_checker_badge" src="https://www<i></i>.mozilla<i></i>.org/img/covehead/plugincheck/wb/en-US/180_150/loading<i></i>.png" width="180" height="150" alt="We can check your plugins and stuff" border="0" /&gt;&lt;/a&gt;&lt;script type="text/javascript"&gt;var pfsNextImage = "https://www<i></i>.mozilla<i></i>.org/img/covehead/plugincheck/wb/en-US/180_150/safe.png";var pfsUpdateImage = "https://www<i></i>.mozilla<i></i>.org/img/covehead/plugincheck/wb/en-US/180_150/upyourplug.png";&lt;/script&gt;&lt;script src="https://www<i></i>.mozilla<i></i>.org/js/plugincheck_badge.js"&gt;&lt;/script&gt;</pre>

Thanks for replying. My blog is at http://adeunsheep.wordpress.com/
You will see two versions of the badge on my blog, on the right sidebar. One is 'cleaned up' where I've removed the script tag (and the link seems to work fine), the other, further down, shows the badge with the whole text including the script tag.
Not sure what "inspect the page source" means but I've tried both 'view page source' and 'inspect element' on the text both on the Firefox page where I found the badge and on my blog (from within the widget placing area, on the blog itself logged in and logged out);
'view page source' shows red text, namely numbers preceded by a #, forward slashes (/), &amp, &gt, &nbsp; (there's also a lot of blue and purple, and some bold black);
'inspect element' shows no red text.
As I say, I've found a workaround but figured it was worth pointing out. I must admit I don't understand how the link works without the script tag but then, I'm a complete novice where code of any sort is concerned!
