* Yes; ASSuME i can get the data entered in the form fields, i want to 
test according to certain criteria and REJECT the "e-mail" attempt.

* Well,the assignment does that. I used the name EBody  for the array; 
could have mixed the character cases at randumb for all javascript cares.

* I know absolutely NOTHING how forms work.

* Stolen coding that i am fiddling with in futile attempts to get info 
from form to javascript.

   Note: input type="email"; the browser must be doing the checking for 
an "@" sign - input must be like x@x and not xxx.

* Again,stolen code. Removing the id= totally makes zero difference.

* OK, it was a statement. _HOW_ do i get this to work?
   Code stolen from http://www.oil4lessllc.com/index-4.html.

* Yes; online guides indicated a message field/block is an array; that 
reading from a multi-line field/block is done by a set (array) of elements.
   I could change that, but the change will not fix the rest of the 
problems.

   How can i transfer the data?

   Thanks.
