  Try this:
  
  (..)
  frxReport1.Variables.Variables:= userId;
  frxReport1.PrepareReport;
  frxReport1.ShowReport();
  (...)

  check this line
  
  frxReport1.LoadFromFile(path + 'forms\DAYReport.fr3' );
  you may need a backslash before forms if it is a subfolder to the apps folder
  were your variables created as categorized variables or typed variables ?
  if categorized variables delete the second .Variables.
  frxReport1.Variables.Variables:= '''' + dateToStr(datetimepicker1.date) + '''';

  Sorry but it didn't worked. Even if I use the following script
  procedure TfrmStatistic.BitBtn1Click(Sender: TObject);
  var path : String;
  begin
  Path := ExtractFilePath(ParamStr(0));
  frxReport1.LoadFromFile(path + 'forms\graph.fr3' );
  // frxReport1.PrepareReport;
  frxReport1.ShowReport();
  end;
  and call fast report via delphi my fast report file opens but no graph appears. I made a graph using as datasource ''fixed data'' option from the graph menu. When I open it by double clicking the fast report file the file opens and my graph appears. But when i call it via delphi ''stol.exe'' file using the above script my fast report file opens, everything appears (headers, footers, etc) exept my graph. Instand of it a white box appears in its position. I' m sure that the fault isn't the graph properties because my graph appears when I open the same fast report file directly.

  In that case i would check to see if your app is calling the correct report.

  I've just made a test using pure FR script in a simple report that had one purpose: load from file and save to file 2 other as simple as possible reports. One of them had a graph inside, while the other hadn't. The script is bellow (button OnClick event)
  

  procedure BitBtn1OnClick(Sender: TfrxComponent);
  var   MyReport1, MyReport2 :TfrxReport;                                                                       
  begin
     MyReport1 := TfrxReport.Create(Sender);
     MyReport1.LoadFromFile( 'c:\temp\graph report to load.fr3' );
     MyReport1.SaveToFile(   'c:\temp\graph report to load(2).fr3' );
  
     MyReport2 := TfrxReport.Create(Sender);
     MyReport2.LoadFromFile( 'c:\temp\report without a graph.fr3' );
     MyReport2.SaveToFile(   'c:\temp\report without a graph(2).fr3' );
  end;
  

  
  And what happend?
  The second report (the one with no graph) written to disk works as an original one - in fact it has a few bytes less.
  The first one (with graph based on 3 fixed data: 1, 2, 3) after writting to disk is completly broken. Instead of about 3kB (as original one) it is about 0,5 kB. When I open it I can see there is NO DialogPage1 and Page1 tab at all.
  
  Maybe this will show you the way of further tests.

  In my opinion, the test I've done proved that there was something WRONG inside Fast Report.
  I mean the operation of loading report with graph may have a bug [img]style_emoticons/<#EMO_DIR#>/sad.gif" style="vertical-align:middle" emoid=":(" border="0" alt="sad.gif" /> You should send a support ticket to Fast Report. Mick[/img]

  Thanks Mick, I'll contact to fast report but could you first send me the script example that you checked to compare it with mine? Thanks.

  Strange things happen [img]style_emoticons/<#EMO_DIR#>/ohmy.gif" style="vertical-align:middle" emoid=":o" border="0" alt="ohmy.gif" /> I did those tests again few minutes ago and it worked correctly. I used a compiled FR4 demo 4.10.14. Then I tested it with our compiled designer that we use to create reports - it worked correctly as well. The last try was made with an application made for customers (compiled exe with no designer). The application can load a report from disk. All those three tests ended with succes[/img][img]style_emoticons/<#EMO_DIR#>/smile.gif" style="vertical-align:middle" emoid=":)" border="0" alt="smile.gif" /> And I couldn't get the wrong results I had few days ago. Both reports to be loaded (without a graph, and with graph) works fine. Here you have my examples. Mick[/img]
