  This code should work. Check your code and script

  I figured out that is DOES work when standing alone.
  In order not to show a blank child band if the only contained field is empty though, I use this code in OnBeforePrint:

  wrote:

  if <frxDBqPacklist."Comment"> = '' then
  Child1.visible := false
  else
  Child1.visible := true

  
  This of renders the setting in Delphi obsolete, of course.
  
  Is there a simple way not to show a empty child band?
  Or how could I tell FR that the above code should only be executed if child1 shall be displayed at all?
  (It is an optional information that the user chooses to display or not display before print)

  Use in the Delphi:

  frxReport1.Script.Variables['HideChild'] := False;
  

  in the script:

  if (<frxDBqPacklist."Comment"> = '') or (HideChild) then
  Child1.visible := false
  else
  Child1.visible := true

  ... thanks gpi.
  
  When I put:
  

  wrote:

  var
  HideChild1: TfrxVariable;

  
  in Delphi, I get an "undefinied identifier" error.
  
  Do I need to add a library to uses?
  
  It seems as if i don't declare HideChild1 variable I get an undefined identifer in FR.
  
  Also, adding Hidechild1 variable in FR does not help (screenshot).
  ?

  frxReport1.Script.Variables['HideChild'] := False;
  

  Add script (not report) variable. Use my code only

  This script will be works in the run-time only.
  If you want - you may use report variable instead of script variable
