[thelist] Form action = $PHP_SELF

[Joshua Hmielowski]

thanks for the input Rodrigo.

fortunately the first thing I tried was " action = ''  " .
I guess leaving the action blank worked well for what I was trying to  
do. everything was fine. (Thanks Roger)
however I will be hanging on to your reply for further reference
