title: Cognos 8.3: Can I use parameters in conditional style expressions?
body: <p>I have Start Date and End date parameters that work fine as filters on a query, as follows:</p>
  
  <pre><code>[EMR Reporting].[Appointments].[Appointment Date] between ?Start Date? and ?End Date?
  </code></pre>
  
  <p>But when I attempt to apply conditional styles to a field based on ?Start Date?, the report blows up.</p>
  
  <p>Should I be able to use parameter values in conditional style expressions, or is this not supported for some reason?</p>
  
  <p>Thanks!</p>
