<INPUT TYPE="checkbox" NAME="snif0" checked="yes" >emA
<INPUT TYPE="checkbox" NAME="snif1" checked="no" >emB
<INPUT TYPE="checkbox" NAME="snif2" checked="no" >emC
<INPUT TYPE="checkbox" NAME="snif3" checked="yes" >emD

If the boxes are checked then add to array @sniffList.  So @snifList should have emA and emD?

Oh, sorry 'bout that, here is the full source for the perl script.
#!/usr/bin/perl

use CGI qw(:standard);
use CGI::Carp qw(warningsToBrowser fatalsToBrowser);

print header;
print start_html;

my @snif= param('snif');
foreach my $snif(@snif) {
   print "You picked $snif.<br>\n";
}


print end_html;
