title: Suppress doesn't work in Crystal Reports 2008
body: <p>i need to suppress column-1 values, if another column-2 was not changed.</p>
  
  <p>i put formula to suppress column-1 like</p>
  
  <pre><code>if {Column-2}=previous({Column-2}) then true else false
  </code></pre>
  
  <p>but sometimes it is not suppressing. I even showed in the report values of <strong>previous({Column-2})</strong> to make sure they are changed</p>
  
  <p>Can you advise, what am i doing wrong?</p>
