Go ahead and name them zzz as before but without the carriage return. Now conditionally format the field so that if it contains the text string zzz the font color changes to transparent.
Or you can add a calculation field with an expression such as:
IsEmpty ( NameFieldHere )
and number as a result type. Sort your records first by this calculation field, then by your name field.
Thanks, Steve! That's great. Hmmm... I wonder how many other little glitches for which I've been creating work-arounds for all these years could be solved using 'Conditional formatting'?! OK, I will admit, I should have kept up with the upgrades - now I'm paying for it! Thanks again!
