Maybe anyone could spot a problem that could fix it ...

Ideas anyone ???? :)

I am seeing a syntax error in Chrome. I don't know how well you know chrome, but if you just hit Cntrl-Shift-j you will get the javascript console which shows the error.

});
</script>

I deleted: });

and no longer get the error.

EDIT: instead of using nth-child which isn't working, try: var index = $this.parent().prevAll().length

change

if($(this).parent().is('.product form .variant_box_option:nth-child(1)'))

to

if($this.parent().prevAll().length == 0)
