i am using cgi.pm to pull the returned values for a web-based form with the following code:

## grab form input
my $query = CGI->new(); 

## grab form field and stick values in hash
my @formfields = $query->param;

for my $field(@formfields) {
  if (  $field eq 'recipient'           ||
        $field eq 'replyaddr'           ||
        $field eq 'required'            ||
        $field eq 'replyname'           ||
        $field eq 'title'               ||
        $field eq 'redirect'            ||
        $field eq 'subject'             ||
        $field eq 'postdir'             ||
        $field eq 'body_message'        ||
        $field eq 'return_link_title'   ||
        $field eq 'return_link_url' ) {

        $CONFIG{$field} = $query->param($field);

  } else {
        $FORM{$field} = $query->param($field);
    
  }

}

now, this seems to work fine and the values are stuffed into one of two seperate hashes. now i look through the %form hash and verify that all the form fields that i mark as required, are filled in

  ## each missed field is placed in a new array
  for my $i(@required) {
    chomp $i;
    if (!$FORM{$i}) {
      push @missed_fields, $i;
    }
  }

the @required array just simply a list of the form fields that need to be present.

what is odd is that sometimes, even though all the form fields have been filled in, the script pushes _all_ the form's fields into @misssed_fields as though cgi.pm hasnt extract any values for them. this seems to occur when a group of radio buttons are selected. it occurs whether or not the radio button form names are within the @required array or not. just having them selected seems to cause cgi.pm to freak.

does this sound at all logical or as a known issue? i can barely believe that it would since i would imagine that many sights are using radio buttons! the form is not especially large, only 30 fields to fill in. your input is very appreciated on this one!
