[Javascript] Trying to get this code to work

[GH]

Greetings. I got this code for a Fade-In slide show  from a depository
of code I have been trying to modify it so that I can have 2 instances
run at the same time on the same page with 2 diffrent sets of images.

What i did was append 'nyc_' infront of the variable and user defined
functions for the 1st instance..  and 'fed_'  for the 2nd instance.

The second instance shows up. But the 1st instance does not... only a
blank space the equivalent to the the space it should use is there.

Please assit. if there is anything that anyone can suggest, I would be
greatful. I have the code for instance 1 listed at
http://phpaste.com/537 with line numbers.... thank you.
