Hello,
I have one problem ( actually I'm sure I have many but haven't
realised it yet ) that I'm stuck on.
the following line ( and several others like it ) produce the
following error :
( my $mollusc ) = ( param( 'mollusc ) =~ /^(\w+)$/i );
causes:

You sound desperate. I am not able to write a suitable script myself
(lack of knowledge and time ) but o'reillys cgi with perl book has a
basic shopping cart in it ( though not if I remember correctly ) with
mysql.
Hope this helps

If you look at O'Reilly's cgi programming with perl book there is a
mechanism there which can be modified to do exactly what you want.
The following was adapted from it :
# initialise subject listings one section per subdirectory under

Hi,
The following line returns a value of 1 (one) - presumably to confirm
a match. What am I missing such that $subject contains the value of
the param ( if matches ).
( my $subject ) = ( param( 'subject' ) =~ /^(\w+)$/i ) || '';
TIA

Hi,
I have just spent two hours trying to figure out why a perfectly good
script had failed!! The old script headers error.

the #!. The space is, of course covered by the cursor when I visit
the beginning of the file
Most ( ? all ) of the distributions have specific mailing lists. I
subscribe to the SuSE list which is excellent. Once you have made the
change you will never want to go back. Good luck.

I have a script which collects a comment than should write it to a

Thank you very much for that. I am amazed at how you find the time to

Hi again,
the script now reads ( see below ) but I still get errors as follows:

How should I initialise those values?
