Re: passing variables from one form to another using Perl

I finally got it.  I isolated the content of the value statement on a line
by itself so I could debug it easier.  The final code that works is:

print "".$ON."\n" ; where $ON is the variable.

Thanks to you and Doug Franklin for your help.

disclaimer: i dont know perl
assumption: the code:
  $ON = $field{'ON'} ; #Category
is correct in obtaining the value of the named field.

with that said, your code should work. i recommend encompassing your VALUE
attribute with double quotes. also, make sure (via the source) that whats
being written from $ON does not contain any quotes itself. if so, i
recommend replacing them with HTML equivalents or just HTML encoding the
entire line (i'm not even sure if perl has such a thing, but im sure you
could write one). for example, if $ON contained the string foo"bar" and you
wanted that to appear in the next form, the HTML should read <INPUT
NAME="data1" VALUE="foo&quot;bar&quot;">. is this your problem? also, i try
to always use double quotes in HTML as well as scripting for strings of any
kind, and i escape any quote contained by the string. i guess its just habit
from Java, but its safer than trying to put doublequotes into single quotes.
