Somewhere in your code you are passing some values to the template 
module incorrectly.  HTML::Template thinks you are trying to set a 
template parameter called '<input type="checkbox" name...', which you 
probably mean to be a value, not a parameter name.

And here is the culprit.  From the CGI.pm docs:

   The value returned by checkbox_group() is actually
   an array of button elements.

So you are sending the following to the template:

$template->param('fetchwhat' => checkbox1, checkbox2, checkbox3);

Which means that checkbox2 is going to be a variable name, and checkbox3 
its value.  what you need to do is join them together into one value.

   $template->param('fetchwhat' => join('', $q->checkbox_group(
              -name=>'fetchwhat',
              -values=>['Database Cross-references',
                    'Blat Hits',
                    'Ensembl Mapping Information',],
              -defaults=>['Database Cross-references'],
              -linebreak=>0)));


Hope that helps...

Cheers,

Cees
