title: Cognos Report Studio Error Invalid to Compare Sets
body: <p>I am using Cognos Report Studio in Cognos 10.2.2. I am trying to create conditional rendering by displaying text the same color as the background (for the purpose of not suppressing a crosstab space) when certain conditions are met. It apppears to work fine with one variable but when I start adding more I get the following error:</p>
  
  <p><code>Invalid to compare Sets in expression for a dataItem="Render Other Expenses".</code></p>
  
  <p><code>CAF-WRN-2082 An error has occurred. Please contact your administrator. The complete error has been logged by CAF with SecureErrorID:2018-02-21-08:04:14.085-#92</code></p>
  
  <p>All of my variables are based on data items with the following structure:</p>
  
  <pre><code>IF( 
      ((completetuple([Item1],[ItemA],[Measure], CurrentMember([Heirarchy])) + 
       (completetuple([Item1],[ItemB],[Measure], CurrentMember([Heirarchy])))=0
  THEN
      (0)
  ELSE
      (1)
  </code></pre>
  
  <p>Any help would be greatly appreciated!</p>
