Hi. I meant install the FireBug extension in FireFox and use it to add
breakpoints in the code and watch variables. Hope this clarifies
things...

I'm loading both into the browser with the different methods, and I can from firebug that the file is getting loaded, but it's not being displayed. Thus, if I re-sent my auto-center to sites2.events, it doesn't center at all. I'm not sure what going wrong here, I thought I'd followed the examples pretty closely. Thanks (again) in advance.
