Rails spinoffs - May 2006 - Making the JS_Slideshow autoplay

I am trying to make the JS_Slideshow auto play through images in the array

http://www.couloir.org/js_slideshow/

I have been looking at the quote fader script used on

http://rubyonrails.com/

all I have managed to do is cycle through the array with the script , 
now images show up and an error is repeated highlighted in the effects 
script

any pointers suggestions would be appreciated


thanks in advance - Sam
