  <p>Works Fine:</p>
  
  <pre><code>&lt;a href="geo:?daddr=21.146677,79.1279979"&gt;{{ orderByInfo?.address }} - 12&lt;/a&gt;
  </code></pre>
  
  <p>Does not open [retailerLat variable with fixed value]</p>
  
  <pre><code>&lt;a href="geo:?daddr={{retailerLat}},79.1279979"&gt;{{ orderByInfo?.address }} - 12&lt;/a&gt;
  </code></pre>
