There's also a TfrxSysMemoView called TypeMemo. I defined a variable called TypeLabel, I fill it up in before I call PrepareReport. When the variable is emtpy (''), I don't want to print the TypeShape. When the variable TypeLabel is not empty, I want to print it's value as well as the shape. Here's is the "OnBeforePrint" code of TypeShape, this is the way I used to do this in QR. However in FR it doesn't work![/img]

  procedure rtTypeOnBeforePrint(Sender: TfrxComponent);
  begin
  if frxGlobalVariables <> '' then
  begin
  TypeShape.Visible := true;
  TypeMemo.Memo.Clear;
  TypeMemo.Memo.Add(frxGlobalVariables);
  TypeMemo.Visible := true;
  end;
  end;

  What I'm doing wrong?? Or how can I access the variables from the PascalScript in my report?
  
  Please just don't tell me to take a look at the demos - I know them all line by line, I read several times all the Manuals, but no luck... As I wrote above, FR is a great tool, but it's big let down is the lack of appropriate manual

  
  
  if Get('myvariable') <> '' then... Variable can be set in a similar fashion - Set('myvariable','TempValue');
  Good luck...

  Hi,
  
  Here's how I access variable
  
  Report.variables
  
  ex: TfrxMemoView(Sender).Memo.Text := Report.variables ;
  
  Hope it helps
