title: Crystal Report Group sort formula
body: <p>I have set the group sort formula and it is working fine, but every time the report runs it ask for the value for the parameter, I already have a field in my report which holds the sort value, I want to set parameter value to this field but no success, every time a prompt appears and I have to write the Sort Value again and then it is working.</p>
  
  <pre><code>if{?Sort}="Mortgage Advisor Ascending"
  then 
  crAscendingOrder else crDescendingOrder
  </code></pre>
  
  <p>Any way out by which I can set the value to this field?
  Do I have to write a formula to set this field to this parameter as well? If yes how and where?
  My formula for equating is:</p>
  
  <pre><code>{ActiveApplicationsReportDT.SortField} = {?Sort}
  </code></pre>
