Question: 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 exact number of tweets. But the problem is that in that case I can use only one link.
To retrieve specific blog page url I use `<data:blog.url/>`. But if i use it in tw:counturl in the following way:

`tw:counturl="<data:blog.url/>"` it shows as an error as tw:counturl cannot handle '<' tag. Is there a work around.

The error is as follows `The value of attribute "tw:counturl" associated with an element type "null" must not contain the '<' character.`

Answer: 
Ok I found the answer to it.
You have to add a javascript code to handle it.

```
var tweet_button = document.getElementById(&#39;addthis_button_tweet&#39;);
tweet_button.setAttribute(&#39;tw:counturl&#39;, <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.
