Question : Justifying Text, HELP!

I making an enhancement to a report in report builder.  There is a field on my layout that needs to be left justified if it satisfies a certain condition.  I've tried to use a CF, but no luck.  I've also tried using the format trigger...no luck.  What am I not doing?

My logic is as follows:

If [condition] = 'Y'
  [left justify text]
else
  [print text as normal]

Any help would be apprecitated

Answer : Justifying Text, HELP!

The format trigger works. Here's an example of a trigger that left justifies odd values and right justifies even values:

function F_rownumFormatTrigger return boolean is
begin
  IF TRUNC(:rownum/2) <> :rownum/2 THEN
    SRW.SET_JUSTIFICATION(SRW.LEFT_HJUST);
  ELSE
    SRW.SET_JUSTIFICATION(SRW.RIGHT_HJUST);
  END IF;
  return (TRUE);
end;
