I am using Flexslider2 with Carousel Slider as navigation here: http://sproutdesigns.co.uk/clients/pim/property.html
However when the thumbnail goes to the second slide it isn't adding the class "flex-active-slide". It is working on all other slides but not this second slide.
I can't see any errors occurring, so not sure why it is happening, can anyone help?
Here is the example I have based this upon: http://flexslider.woothemes.com/thumbnail-slider.html
