Dave,

I have added the content with the code above to the website and the button shows just fine.

The problem that I am having now is that when I click on send an e-mail or bookmark instead of the URL showing it shows the [url]. So it will not add to favorites or display the link when you click on send an e-mail. I suspect when social bookmarking it won't show the URL as well just the value for URL.

Is this because the single quotes are escaped? This works on all my other php sites but I didn't have to escape my single quotes code. Please visit this page: http://www.lasilhouettelingerie.com/store/ and give it a try. For some reason it is not inserting the URL for the url value.

Here is the exact code that I used:
Code:
/* Your html and/or javascript code goes between the 2 single quotes in the next line */
$content = '<div id="absolutelinksContent" class="sideBoxContent centeredContent">';
$content .= '<!-- AddThis Button BEGIN -->';
$content .= '<script type="text/javascript">var addthis_pub  = "lasilhouette";</script>';
$content .= '<a href="http://www.addthis.com/bookmark.php" onmouseover="return addthis_open(this, \'\', \'[url]\', \'[TITLE]\')" onmouseout="addthis_close()" onclick="return addthis_sendto()"><img src="http://s7.addthis.com/button1-bm.gif" width="125" height="16" border="0" alt="" /></a><script type="text/javascript" src="http://s7.addthis.com/js/152/addthis_widget.js"></script>';
$content .= '<!-- AddThis Button END -->';
$content .= '</div>';
