M:   @lists = split(/ /,param('list'));

from perldoc CGI:

FETCHING THE VALUE OR VALUES OF A SINGLE NAMED PARAMETER:

   @values = $query-param('foo');

 -or-

   $value = $query-param('foo');

Re: multiple selection

[Jason Purdy]

Two things:
1) Your action parameter of the form tag was pointing to a separate program.
If you leave it blank (or leave it out altogether), then this same script
will process it.
2) You don't need to split param('list') - CGI.pm will automatically make an
array for you, if it contains multiple entries.

HTH  Have Fun!

 Hello all,

 having a problem with processing multiple selection from a scrolling
list...
 first time working with tha scrolling list. Here is the test script I'm
working
 with:
 #!/usr/local/bin/perl
 use CGI qw(:standard);

 $action = param('action');

 print header();
 print start_html();
   if (!$action) {
 print start_html();
 print qq~
 form method=POST action=/mailer/cgi/list.pl
 input type=hidden name=action value=doit
 font face=arial size=2BSelect List:/BP
 ~;
 print scrolling_list(-name='list',
   -value=['List_1','List_2','List_3'],
   -default=['List_1'],
   -multiple=1);
 print qq~
 input type=submit value=Submit/form
 ~;
 print end_html();
} else {
@lists = split(/ /,param('list'));
 print qq|Total: @lists|;
}

 exit();

 Now I thought that the @list array would store all the selected values
from the
 list... but it doesn't, just one, even if all the items have been selected
from
 the list... what am I missing here ??

 thanks
