[jQuery] Hover on different ids

[Geir]

Hi!
I want an div#breadcrumb to animate when some other divs are hovered.
This is my code:

        var BrHo = $('#breadcumb') + $('#nKnapper') + $('#Navigation');
        BrHo.hover(function(){
                $('#Breadcumb').animate({
                opacity: '1',
                fontSize: '14px',
                }, 2000)
    }, function(){
                $('#Breadcumb').animate({
                opacity: '0.1',
                fontSize: '10px',
                }, 2000)
        });

It's not working.
It seems like I have to convert BrHo variable to an Array? Is that
right?
