[Omaha.pm] CGI.pm param() gotcha

[Jay Hannah]

20 bonus points to anyone who can tell me why I made this change:

255,261c255,261
<   $res->set_address    (address1     => $q->param('gst_addr1'),
<                         address2     => $q->param('gst_addr2'),
<                         address3     => $q->param('gst_addr3'),
<                         city         => $q->param('gst_city'),
<                         state        => $q->param('gst_state'),
<                         postal       => $q->param('gst_zipcode'),
<                         country_code => 
$q->param('gst_country_code'));

 >   $res->set_address    (address1     => 
scalar($q->param('gst_addr1')),
 >                         address2     => 
scalar($q->param('gst_addr2')),
 >                         address3     => 
scalar($q->param('gst_addr3')),
 >                         city         => scalar($q->param('gst_city')),
 >                         state        => 
scalar($q->param('gst_state')),
 >                         postal       => 
scalar($q->param('gst_zipcode')),
 >                         country_code => 
scalar($q->param('gst_country_code')));

Hint: $q->param('gst_addr3') is undefined.
