Need help with a share button for my blog

[CharlesCS]

I hope this is posted on the correct section of this site.

I am trying to find a code that will share my blog articles as a "tweet this" to peoples twitter sites (with the short address feature from TinyURL) when they click a button I have on my articles. the problem is the site I blog on, www.joeuser.com, is not very script friendly so I cant use buttons from sites like retweet.com. joeuser.com just won't recognize codes that have scripts like this one:

&lt;script type="text/javascript" src="https://www.retweet.com/static/retweets.js"></script>

I can however used codes like this one:

<a href="http://digg.com/submit" onclick="window.location = 'http://digg.com/submit?url=' + encodeURIComponent(window.location); return false"> <img src="https://img692.imageshack.us/img692/4878/digglogowebtreatsetc.png" width="48" height="48" alt="Submit To Digg" border="0" /></a>

It's when the code says script that it gives me problems. Is there a code that looks like the one above but works like the one on top? For an idea of what buttons I am talking about you can check one of my articles at charles.joeuser.com and look for the buttons at the bottom. The facebook one works great, it gives people the option to post the articles to peoples facebook when they click the button. Any help would be appreciated.

Thanks in advance.
