DHTML Script Error - Undefined

I keep getting the word "undefined" displayed instead of the intended text
in the up-scrolling animated script located in the upper-left hand corner of
this work-in-progress:

http://www.marymoorvelodrome.org/new%5Fsite/index.html

Can anyone tell me what causes this? If I hit refresh, my intended text
comes back. Then, "undefined" appears, and repeats indefinitely.

Any help?

Thanks!

Thanks, I'll give it a try.

I was afraid it was something to do with the fact that I only have two
messages out of potentially many more.

It looks like it's getting confused by the fact you only have two
scrolling messages, and it's going past the end. Try replacing all
occurances of:

if (i==messages.length-1)

with:

if (i>=messages.length-1)

I don't promise it'll work though - it's obviously designed to have
more messages.

Well, that did it!

Fixed!

Stephen:

Almost fixed. We ALMOST have it - I get only ONE "undefined", after
applying your fix and editing that one "if" statement. I can't see any
others to fix using Find-Replace

"Undefined" appears once, and then the regular text comes back.

Can you offer a suggestion? Or an alternative method of displaying this
scrolling text?

Thanks!

Now if only all programmers would learn to use the correct
termination-conditions... [dreams of a world with well-named variables,
documentation, buffer overrun checks...]
