  Look at what you passed in in the ongetvalue event.
  you probably included a [ within the string.

  No, the value that i obtain is ok.
  
  This is my code :
  

  procedure OnGetValue :
  begin
     if AnsiComparetext(VarName, 'var1') = 0 then
       Value := 'coucou';
  end;
  

  
  In my report, the variable's value is in a TFrxmemo.
  But when i want to do a copy(Memo3.text,1,6), it shows me "[var1]" instead of "coucou".
  
  I've tryed "copy([var1],1,6)" but an error message appears "Undeclared identifier <cell1>". I've also tested without [] but it's similar.

  ok what you are doing is trying to copy the memos.text property which is [var1], u
  you want the value of the variableand you must watch 2 things,
  since you are retrieving the value of the var in the ongetvalue event you can't process it until after it retrieves a value. so write your expression in the memo this way [Copy([var1],1,3)]

  I already tested that but when my report appears, an error message appears too !!
  "Undeclared identifier var1".
  
  My variable is into a Memo in a MasterData and the other Memo where i want to do a copy of my variable is in a GroupFooter, is it important ?

  this assume you created var in report's datadictionary named var1 and did not set any expression value to it.
  your onget value code is bad
  
  should be
  if AnsiComparetext(parName, 'var1') = 0 then
  parValue := 'coucou';

  not with the fastReport version 3.05 !
  
  I've tested on Windows NT4 and an error appears but with Windows XP, I've not got error. Why ?

  if you are using fr3 please post questions for fr3 in fr3 forum
  the answer i gave you was for fr2.53.
  in version 3
  you must use the get method with the variable
  [copy(get('var1'),1,3)]
