Jquery Cycle: Can't navigate through slides

I'm trying to make a slider with jQuery Cycle where, when you click on one of 5 thumbnails, you switch to the right slide in the slider. Those thumbs are external to the slider.

Thing is, for some reason, the startingSlide argument doesn't work and just doing .cycle(number) doesn't either, even if the slider is clearly running. Here's a peek at the code:

JS

        jQuery(document).ready(function(){
        var current_slide;
        jQuery('#slider_accueil').cycle({ 
            fx:     'fade',
            timeout: 3000,
            after: onAfter,
            startingSlide: 0,
            pager: '#nav',
            next: '.next_btn_slider',
            prev: '.prev_btn_slider'
        });

        function onAfter(curr,next,opts){
            jQuery('.indicator').removeClass('current')
            current_slide=opts.currSlide + 1
            jQuery('#thumb'+current_slide+' .indicator').addClass('current')
        }

        jQuery('#thumb1').click(function(){
            jQuery('#slider_accueil').cycle(0);
            return false;
        })

        jQuery('#thumb2').click(function(){
            jQuery('#slider_accueil').cycle(1); 
            return false;
        })

        jQuery('#thumb3').click(function(){
            jQuery('#slider_accueil').cycle(2); 
            return false;
        })

        jQuery('#thumb4').click(function(){
            jQuery('#slider_accueil').cycle(3); 
            return false;
        })

        jQuery('#thumb5').click(function(){
            jQuery('#slider_accueil').cycle(4); 
            return false;
        })
    })

        </div>

^check source, seems I cant put that cleaner than this.

Anybody have an idea?

PS, It's on purpose that all img are ig and all links are ... Stackoverflow wouldn't let me post.

I found the answer to my own question...

Seems that to use jQuery('#slider_accueil').cycle(0); you need to have the full version linked, and not the lite.

Seems like that function is one of those who have been taken out from the conversion from full to lite... Note to self: The lite versions may not have the function you want to do... just spent 2 hours trying all kinds of stuff on that. :p
