dws is right: start_th (or start_td) alone is incorrect.

OR, if you are going to use start_th and start_td, then use end_th and end_td.

So, use this:

$query->th({-align=>'center'}, strong('VOLUNTEER')),

or this:

$query->start_th({-align=>'center'}), strong('VOLUNTEER'), $query->end_th({-align=>'center'}),

instead of this:

$query->start_th({-align=>'center'}), strong('VOLUNTEER'),
