title: How do I relace fields with "yes" or "no" in Crystal Reports based on whether they have a value?
body: <p>All I want to do is change everything in a field that has a value to "Yes" and everything that does not have a value to "No".</p>
  
  <p>I've tried this:</p>
  
  <pre><code>if {CnNote_1.CnNote_1_Description} = "" then "No" else "Yes";
  </code></pre>
  
  <p>But I get an error saying, "The result of selection formula must be a boolean."</p>
  
  <p>If I try:</p>
  
  <pre><code>IF {CnNote_1.CnNote_1_Description} = TRUE then "Yes" else "No";
  </code></pre>
  
  <p>Then I get a error that says, "A string is required here."</p>
  
  <p>This should be a simple thing, what am I doing wrong?</p>
