Here is my line of markup code for Rich Snipets. Google says use it but I didn't find any particular way to make it WORK. I inluded this block of code in both HEAD and BODY areas as said by GOOGLE, but it didn't word either way. I even TESTED it and says no ERRORS. This is of ORGANIZATION type.

<div itemscope itemtype="">
  <span itemprop="name"><strong>YoursVaastu</strong></span>
  <img itemprop="logo" src="" />
  <span itemprop="name">Official Website:</span>
  <a href="" itemprop="url"></a>
<div itemprop="description">YoursVaastu is an online platform to encourage people regarding the application of Vastu while building or purchasing properties.</div>  
  <div itemprop="address" itemscope itemtype="">
    <span itemprop="addressLocality">Kolkata</span>,
    <span itemprop="addressRegion">West Bengal</span>,
    <span itemprop="addressCountry">India</span>
  <span itemprop="name">Founder:</span><a itemprop="url" href="">Satish 


Please, suggest the way I could use the code.
