Adding to the above, please use CGI.pm to make your life a lot easier! And avoid the references - strict will not be happy and it's easy for typos to creep in.

Although you don't explain, I assume you want to be able to read the variables for processing afterwards, so using CGI.pm, here's an example snippet:

my $q = new CGI;

# let's assume the values creating the option html of $fname
# are stored in the array @fnames, and that the values 'GUEST'
# and 'Select a member' have been 'push'd onto the end.

for (0..$elements) {
  $name_menu{$_} = $q->scrolling_list(-name => "M$_",
                                      -values=>[@fnames],
                                      -default=>['Select a member'],
                                      -size=>1
                   );
}

Later, when it comes to accessing the variables sent from the form, transfer them to a hash:

my $i=0;
my %M;
while (my $val = $q->param("M$i") ) {
  $M{$i} = $val;
  $i++;
}

Then all Mi elements are accessable as $M{i}

Hope this is useful.
