Hi, I have this site here

I want to slow down the speed of the slides. It was originally set to 'normal' (being the default). I change this to 'slow' jqueryinnerfade.js file but there is no change. I have tried a variety of numbers and no change. Even when I put it really high or low it doesn't go faster or slower. Usually I don't have any problems changing the speed of sliders.

The only thing I am able to change is the fade speed but I don't want this to change.

Any ideas on how to make it slower? and why it's not changing by the usual means?
