I know whenever you help people with something like this -- you open a can of worms that keeps you busy putting out people's fires.
I followed your distructions and added 6 banners (six different invocation codes) to my 30+ styles at
www.moparstyle.com -- and everything works great.
99.44% of the time when I use one of the hacks here -- everything works fine. When it doesn't -- I generally find a typo on my part when I reread.
This is long way of saying all is well -- and I appreciate your help. Much faster than having the server running all of that Java code.
