I'm using the following code for readers to be able to tweet a specific blog post-\[code\]<a expr:href='"http://twitter.com/home?status=Reading " + dataost.title + " @mytwitter " + dataost.url' class='twitter'></a>.content .share .social ul li a.twitter { display: block; width: 26px; height: 26px; background: url(img/twitter.png); text-indent: -99999px;}.content .share .social ul li a.twitter:hover { background: url(img/twitter-hover.png); background-position: 0 0;}\[/code\]The link isn't working, and doesn't even appear to be active and I'm not quite sure why. Any ideas?
