title: jsfiddle with knockout getting errors
body: <p>I can't figure out what the error in the console means when I run my jsfiddle.</p>
  
  <p><a href="https://jsfiddle.net/rwa03vrb/1/" rel="nofollow noreferrer">Fiddle here</a></p>
  
  <p>And this is the beginning of the error:</p>
  
  <pre><code>    jQuery.Deferred exception: Unable to process binding "foreach: function (){return items }" Message: Unable to process binding "value: function (){return itemNo }" Message: itemNo is not defined
  
  anonymous/&lt;.value@https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.1/knockout-min.js line 68 &gt; Function:1:58 a.d.value.init/m@https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.1/knockout-min.js:102:301 z.Qc@https://cdnjs.cloudflare.com/ajax/libs/knockout/3.4.1/knockout-min.js:51:391
  </code></pre>
  
  <p>That is all in yellow but there is a single red error at the bottom: <code>ReferenceError: itemNo is not defined</code>.  It bugs me that the console never gives relevant line numbers.  I supposed with libraries, partial views, layouts, etc, it makes it difficult.</p>
