Hello everyone,

I've tried searching for this but couldn't find anything that matched
this.

I would like to invoke() the insert() method on an element and insert
a link at the end of every fieldset on my page.

This is my code:

$$('form.form fieldset').invoke('insert',
  new Element('a',{ href: '#' })
  .update('advanced')
  .observe('click', function(event) {
    this.up('form.form').toggleClassName('simple');
  })
);

What happends is that the link is only inserted at the last fieldset
of my page.

Also when I create the link first like:
var link = new Element(...);
and then:
$$('form.form fieldset').invoke('insert',link);
The same thing happends, only the last fieldset gets a link.

Am i really forced to use each() like this?
$$('form.form fieldset').each(function(fieldset) {
  fieldset.insert(new Element(...).update(...).observe(...);
}

I really hope you can tell me what I am doing wrong because I really
want to make the code as good as possible.

Thanks in advance,
 Johan
