title: simpleCart quantity not showing correctly
body: <p>I tried having simpleCart shopping cart display name, price and quantity using the following line  </p>
  
  <pre><code>&lt;a class="item_add" href="javascript:;"&gt; Add to Cart &lt;/a&gt;&lt;/p&gt;
  </code></pre>
  
  <p>as given in documentation and in sample index file included in simplecart.js download. That did not show item name. </p>
  
  <p>Index file also included alternative formulation:</p>
  
  <pre><code>&lt;a href="javascript:;" onclick="simpleCart.add({name:'baby lion', price: 34.95,size:'tiny',thumb:'e.png'});" &gt;add to cart&lt;/a&gt;
  </code></pre>
  
  <p>which added the name, price but wrong quantity. Adding quantity attribute either directly (i.e. <code>quantity: Quantity</code>) or by getElementById method (i.e. <code>quantity: document.getElementById("item_Quantity").value</code>) resulted in errors.</p>
  
  <p>My shopping cart's columns are set up as follows:</p>
  
  <pre><code>simpleCart({
      cartColumns: [
  
  { attr: "name" , label: "Item"},  
  
  { attr: "price" , label: "Price", view: 'currency' } ,
  
  { view: "decrement" , label: false , text: "-" } ,
  
  { attr: "quantity" , label: "Qty" } ,
  
  { view: "increment" , label: false , text: "+" } ,
  
  { attr: "total" , label: "SubTotal", view: 'currency' } ,
  
  { view: "remove" , text: "Remove" , label: false }
      ]
  });
  </code></pre>
  
  <p>How can I show both name and quantity?</p>
