      Greets Peeps,

      Jeff said ---> It's GOOD THAT YOU GET THIS WARNING.
      You're using -w. This helps you debug problems. ---

      Aye, yah, the problem has been figuring out where to
      access the error log. My host keeps it tucked away
      nicely, but once I located it things have been going
      much better. But, I still have to go through a bunch
      of stuff to access it, and it lists the errors in a
      confused, reverse order, so we can see the importance
      of your next point...

      Jeff then said ---> You should probably include

      use CGI::Carp 'fatalsToBrowser';

      at the top of your program so that the 'die' message
      goes to the browser, so it's easier to debug problems.
      ---

      This is good, but I put this line (and only this line
      just as it is written) into the code at the module
      calls, but it didnt do anything new even when I kept
      the errors in place.

      Also, is this part of CGI.pm or a standalone module?

      TFTH!
      =)

        Hmm. It seems to be interpreting your quoted strings as code. That's
        damn odd.

        Are there any single periods on lines by themselves? That tends to
        terminate mail messages, IIRC.

        Can I get a copy of the output?

        Greetings Folks,

        I am getting an error message I cant figure out. Can
        someone tell me what I am doing wrong? Here it is:

        #####################################################

        Here's the actual script. The line numbers are next
        to the comment in parentheses.

        ##### DECLARE MODULES #####

        use strict;
        use CGI;


        ##### DECLARE MODULE OBJECTS #####

        The script accepts input from an HTML form, and it
        runs in so far as it will deliver the mail with all
        the form fields, but it still spits out the error
        message and wont redirect to the next page.

        Any help much appreciated.

        Thanks,

        Will

          I already corrected some of the code, but I am still
          getting those two error messages (in my error logs).
          The script (below) sends the email, and the email
          looks as one would expect it to turn out, but it just
          doesnt list anything in those two variables.

          Using CGI::Carp 'fatalsToBroswer'; wont yield any
          error messages in the browser, but in the error log it
          still shows up (also as quoted below).

          Dunno what's wrong yet, but I'm not done with it
          either. ;)
