That would be the idea, yes. It was some time since worked with
Quick_Form, so there might be a specific order you need to perform the
adding of the rule in relation to the validate() method call on the
$form object.

I am not sure about this, is there even client-side validation support
in Quick_Form? Haven't really looked into this. I would suggest writing
a manual javascript evaluation for the specific fields that should be
visible when the checkbox is checked, or to have a postback between. The
JavaScript option sounds most tempting, since it makes it a bit more
user-friendly. That way you can use the JavaScript alert() function to
present the fields that have erroneous information as well as altering
styles in the fields in question to perhaps have a red border to
indicate errors.
