I have an addthis plugin for displaying total number of tweets in my blogspot blog. I use it this way If i mention tw:counturl=\"my_specific_blogger_url\" > it shows the e
Ok I found the answer to it. You have to add a javascript code to handle it.
var tweet_button = document.getElementById('addthis_button_tweet');
tweet_button.setAttribute('tw:counturl', <data:blog.url/>);
This should work, you just need to add "expr" before tw:counturl. I was able to get it working on my Blogger site with the following:
<a class='addthis_button_tweet' expr:tw:counturl='data:blog.url'/>
This needs to be entered into the template itself Template -> Edit HTML -> Proceed.
I hope this works for you.
