title: Crystal Reports : This group section cannot be printed
body: <p>I'm currently modifying an existing report and replacing the data source used in the report.  The reason I'm not creating a new report is because the report is laid out exactly how I would like it to be laid out.  I've updated every field with the new data source fields and checked that the formulas are all correctly formatted.</p>
  
  <p>Everytime I attempt to view the report (I'm using the Crystal Reports tool in VS 2010), I get the error "The group section cannot be printed because its condition field is nonexistent or invalid.  Format the section to choose another condition field."</p>
  
  <p>I've read another question from stackoverflow but still can't seem to find out what is wrong with my report.</p>
  
  <p>First of all, why doesn't Crystal tell you more specifically what is wrong?</p>
  
  <p>Any suggestions or hints?</p>
