nn4 requires that you make a full reference to objects.  that means you need
to preface your reference to the "frm_search" object with the "document"
object:

document.frm_search.submit();

however, there's a little shortcut you can use since you're calling this
from an event handler on a form element.  there's a keyword called "this"
which refers to the calling object -- in this case the checkbox input.  that
input has a property called "form" which is itself a reference to the parent
form object.  and of course, that form object has a method called submit().
so, you could call it like this:

this.form.submit();

that being said, what are you doing for non-js users?  do they just get left
in the cold staring at a form that won't do anything?  *shakes head in
dispair*
