Changing parameters has no effect on my jQuery slider, where have I gone wrong?

I've been messing around with Nivo Slider but I think I've slipped up somewhere. When trying to change the vaue for the 'controlNav' parameter, I realised that none of the parameters were working. Here is the slider in action. If it was working, then the buttons at the bottom would not appear, as I have set the parameter 'controlN开发者_StackOverflow社区av' to 'false'.

You're initializing nivoSlider twice on the same div. Remove the first call, and the control nav will disappear.
