Fancybox 2 pause button helper

Hi, I have another question / problem..
I’d like to be able to pause the Fancybox slideshow.
Fancybox has a Button helper to add the needed buttons, but I don’t manage to activate the helper.

See the “Button helper” example under “Extended Functionality” here: http://fancyapps.com/fancybox/#examples

I manage to register the needed css and js files, but I fail at including / running the following js options:

$(document).ready(function() {
$(“.fancybox-gallery”).fancybox({
closeBtn : false,
helpers : {
buttons : { position : ‘bottom’ }
}
});
});

Any help very welcome..!
