title: checkout is not working in magento1.7
body: <p>I have a multistore done in <code>Magento 1.7</code>. Checkout is not working in one store. Nothing is happening after clicking the continue button inside <code>Billing Information</code> block which calls the function <code>onclick="billing.save()"</code>. I checked with firebug all blocks are coming correctly. I think the problem is with the function <code>billing.save()</code>. Where I can find this function.</p>
  
  <p><strong><em>EDIT</em></strong></p>
  
  <p>I have checked my response in <code>transport.responseText</code> in <code>billing.save()</code> for one store I am getting response like this</p>

  <p>and for the store which is not working its coming like this</p>
  
  <pre><code>&lt;meta name="google-site-verification" content="xxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxxx" /&gt;

  <p>I don't know from where this meta tag is coming and when I alert <code>response.update_section.name</code> in side  <code>setStepResponse: function(response){</code> its coming as undefined... </p>
  
  <p><strong>EDIT 2</strong></p>
  
  <p>Now meta tag problem has been solved.. They have added that meta tag inside index.php of their sub domain folder.
   <strong>Now the problem is when I place order it displays</strong> </p>

    <p>Gateway error: (TESTMODE) The merchant login ID or password is invalid or the account is inactive.</p>
  </blockquote>
