Blogger Adsense in Posts

Darkphenom

I want to put adsense in posts in my blog. Except I only want these ads to appear when you click on the post and go to the post page itself. I tried different things online including this

<b:if cond='data:blog.url == "Blog Post URL"'>
[ADSENSE CODE HERE]
</b:if>

This just meant that the ad appeared on both the home page and on the post page. How can you get the ad to just appear on the post page??
