title: Operator '=' is not Defined for Type Integer in SSRS
body: <p>I am trying to hide rows in SSRS where Sales values are 0 (zero).
  My expression is:</p>
  
  <pre><code>     =IIF(Fields!SalesYTD = 0,True,False)
  </code></pre>
  
  <p>I am getting the error:
           "Operator '=' is not Defined for Type Integer..."
  How do I implement this logic?</p>
