Thanks, Paul, I've been playing with just that.
    First I chose a location where no use of the function had occurred 
yet. No change.
     Finally I moved it all the way to the top, and it started to work!! 
But my joy was short-lived as when I closed/restarted my browser to kill 
off all session counters etc., the error was back!
    Unfortunately I did two things at once: Moved similar code on the 
preceding page to the very top also (no white space of any kind) 
immediately after session_start. I ran the entire form over and that 
preceding page worked OK, but the original page I queried about, then 
gave me a familiar PHP message:
-----------
Parse error: syntax error, unexpected $end in C:\xampp\htdocs\twa2.php 
on line 112
-----------

Different place in the text, not at the end, but it IS prior to ending 
PHP and starting HTML code!

I should probably tell anyone reading now to Stand Down;
  much as I hate to, I think I'll back up to an archived version that 
WAS working but without most of the validation rules and containing 
preset inputs to make the forms quicker to test.

My thanks to you and I'll be back when this is resolved to explain 
whatever I discover is the danged reason! <g>

Regards,

Twayne`
