Crystal Reports error (RESOLVED)

[divined]

Hello everybody

I have created a Crystal Reports report using the RDC. Then I feed the report with a Recordset. When I try to set it to a Crystal Reports viewer control I get the error.

Cannot determine the queries necessary to get data for this report. This is the code I`m using :

  CrystalReport_episkeyhKlinikhs.Database.SetDataSource rsListaEpiskeywn, 3, 1
  
  Set p1 = CrystalReport_episkeyhKlinikhs.ParameterFields.GetItemByName("Title")
  p1.AddCurrentValue (rsYphresia.Fields("Yphresia").Value)
  

  Set p2 = CrystalReport_episkeyhKlinikhs.ParameterFields.GetItemByName("DateStart")
  p2.AddCurrentValue (strGlobalDateStartEuropeanFormat)
  
  Set p3 = CrystalReport_episkeyhKlinikhs.ParameterFields.GetItemByName("DateEnd")
  p3.AddCurrentValue (strGlobalDateEndEuropeanFormat)
  
  
  Set p4 = CrystalReport_episkeyhKlinikhs.ParameterFields.GetItemByName("Klinikh")
  p4.AddCurrentValue (strGlobalKwd_Klinikhs)
    
 
  crViewer1.ReportSource = CrystalReport_episkeyhKlinikhs
  
  
  CrystalReport_episkeyhKlinikhs.AutoSetUnboundFieldSource crBMTName
  
 
  crViewer1.ViewReport

rsListaEpiskeywn, the Recordset, has at least one record in it. What could be the cause of this error?

thx, in advance

Actually, it seemed to be some intricate and slight error in the report. I copied a working report and then it all fell into place.
