  Tricky one.
  I'd try this:
  Set it to be a DoblePass report, first of all.
  Then all the following is in the scripts of the report:
  Create a global variable to count the number of records, let's say TotalRecs, and one for the current rec, CurrentRecCounter, initialise them with 0.
  Then on the OnBeforePrintEvent of your MasterData band you increase the counter IF it's the first pass, or if it's the FINAL pass, then you set the visibility of your line to true or false:
  
  MasterData.OnBeforePrintEvent
  begin
  if not Engine.FinalPass then
  inc(TotalRecs)
  else begin
  inc(CurrentRecCounter);
  if CurrentRecCounter >= TotalRecs then
  Line1.visible := false
  else
  Line1.visible := true;
  end;
  end;
  
  
  Alternatively, you can skip the inc(TotalRecs) line and initialise it directly with
  TotalRecs := Dataset.recordcount;
  
  I hope it gives you some ideas.

  Also, I think I saw something in the User help files (pdf), go the section that talks about the child objects, you might find something to help with code like this:
  child1.visible := not dataset.eof;
  
  where your line is in the child1 band.

  Basic
  retrieve the recordcount of the dataset store in a variable
  when line# variable = recordcount turn off what you want.
  
  Grouping
  
  since you are using grouping you will have to make the report 2 pass store the count in an array
  just like storing a total to print in the header, only store the count.
  as Anu de Deus has suggested.

  Hi,
  
  Thanks for the help and ideas. It pointed me in the right direction. In my final solution, I followed the "Total in Group header" example somewhat.
  Not fully understanding how the variables were being reset in the events, I had to play around initially. I also added a group footer, which I didn't need (so I just set its Visible property to False on the FinalPass - not sure if it needs to be visible for the OnBeforePrint to be called, so left it there for the first pass).
  Anyways, below is the code I finally implemented:
  
  var
  slGrpList: TStringList;
  iGrpRecCount: integer;
  iGrpCount: integer;
  
  procedure frxInvoiceOnStartReport(Sender: TfrxComponent);
  begin
  iGrpRecCount:= 0;
  iGrpCount:= 0;
  iRecID := 0;
  slGrpList:= TStringList.Create;
  end;
  
  procedure frxInvoiceOnStopReport(Sender: TfrxComponent);
  begin
  slGrpList.Free;
  end;
  
  procedure GroupFooter1OnBeforePrint(Sender: TfrxComponent);
  begin
  if not Engine.FinalPass then
  begin
  List.Add(IntToStr(iGrpRecCount));
  iGrpRecCount:= 0;
  end;
  Inc(iGrpCount);
  iRecID := 0;
  if Engine.FinalPass then
  GroupFooter1.Visible := False;
  end;
  
  
  procedure MasterData11OnBeforePrint(Sender: TfrxComponent);
  begin
  if not Engine.FinalPass then
  begin
  inc(iGrpRecCount);
  end
  else
  begin
  Inc(iRecID );
  if iRecID = StrToInt(List[iGrpCount-List.Count]) then // note this, the iGrpCount variable was always working out to twice the actual list count, hence the subtraction
  Line33.visible := false
  else
  Line33.visible := true;
  end;
  
  Anyway, thanks for the suggestions. I got it to work!

  A maybe dirty but simpler one?
  

  procedure MasterData1OnBeforePrint(Sender: TfrxComponent);
  var 
    OldGroupValue :Integer;
  begin
    OldGroupValue := <Data."GroupID">;                                                    
    MasterData1.DataSet.Next;
    Line33.visible := (OldGroupValue = <Data."GroupID">) and not MasterData1.DataSet.Eof;
    If not MasterData1.DataSet.Eof then                                 
      MasterData1.DataSet.Prior;                                                                   
  end;
  

  
  No need 2 pass, no need variable, simple code in one function.
  I am not very familiar with FR coding though so I don't know it had bad effect or not...
