I don't understand this error

[jaschulz]

I have been trying to study some code I found at:

http://www.webreference.com/programming/javascript/gr/column3/

for preloading images. The demo site described on the page above no longer exists, so I had to build my own from the article. I did that, and you can see it at:

http://www.wiseware.com/test/

Firebug gives the following error(s), when the page is loaded:

missing ) after formal parameters [Break on this error] function ImagePreloader(images, call-back) {\n ImagePreloader.js (line 1)

ImagePreloader is not defined

I cannot see why Firebug thinks a parenthesis is missing.

What am I missing?

Thanks,

James

Why is there a minus sign in one of the variable names: call-back?

Thanks, Lee. I don't know how I missed that.
