body: <p>If I am putting value in received cases 0 then its not giving any value no subtraction performing</p>
  <pre><code>let _variance = _receivedCases - _requestedCases;
   
  document.getElementById(&quot;Variance_&quot; + index).innerText = _variance;
  if(_variance === 0){
     $(&quot;#Variance_&quot; + index).parent().removeClass(&quot;text-danger&quot;);
  }
  else{
     $(&quot;#Variance_&quot; + index).parent().addClass(&quot;text-danger&quot;);
  }
