Caveat Coder

2 easy mistakes to make with regards to the output string:


    sub start {

        # ....

        $output .= $webapp->drink_type_form;
        $output  = $query->end_html;

        return $output;
    }

$output now only equals end_html().

Beware using '=' when you want '.='

Also, ',' when you want '.' is a problem:


       $output .= "a", "b", "c", "d";

       # Perl will treat this as:

       ($output .= "a"), "b", "c", "d";

(Using templates will minimize this risk...)
