I'll outline what I'm attemping to do just in case I'm misguided. This is a web application using CGI.pm and HTML::Template

In a module I create a hash

our %cgi_vars = $q->Vars;  ## Collects all my form data

Within a .cgi script, I update values in the %cgi_vars hash and now want to transfer the new values into my .tmpl using associate. In order to do this, I (think) I need to put the values back into the $q->param() object.

 
foreach (keys %cgi_vars) { $q->param($_ => $cgi_vars{$_}); }

This all seems to work until the value of $cgi_vars($_) = "". In that case the value remained unchanged, so I did some testing with just 1 element...

## This worked
if ($cgi_vars{fname}) {
    $q->param('fname' => $cgi_vars{fname});
} else {
    $q->param('fname' => "");
}
## But this did not
$q->param('fname' => $cgi_vars{fname});

Could someone explain where I'm going astray? Or maybe there's a better way to deal with this
