Hi Everyone!

I'm trying to figure out how this custom jQuery functions work by experimenting a bit. I can't however get it to work properly. I'm trying to call the prepareSlide 

function in my setInterval but it says prepareSlide is not defined

$('document').ready(function(){

    jQuery('.item_holder').itemSlider({

        start: 1,

        carousel: true

    });

});

$.fn.itemSlider = function (details) {

    var currentSlideNumber = (details && details.start > 0) ? details.start : 1;

    this.prepareSlide = function(slideNumber) {

        alert(1)

    }

    //Set an interval

    var itemToSlide = currentSlideNumber + 1;

    slideTimer = setInterval("prepareSlide(" + itemToSlide + ")", 5000);

}

Please help me!

Thanks in advance!
