The place to implement logic based form_set_error should be in the validate
function and not template.php .. I would recommend you use
$form_id will indicate the form you wish to alter, and there you can
a custom validate function in $form['#validate'] -- the custom function
should then take care of form_set_error
you need to set the element name as first parameter to make sure that
the particular field is highlighted.
