You need get_all_element(), which does a recursive search.

get_element() only searches elements which are direct children of
whatever you're searching.
(and if you're searching a form with auto_fieldset(1), then
get_element() will only ever return the fieldset)

You want get_all_element() - not get_all_elements()

The first returns a single element - the second returns an arrayref of
elements, even if there's only 1 to return.
