Thanks Ralf,
After taking a break for a bit, and getting a fresh look at my code, I saw
the difference in cases, and actually managed to figure out the placement
of braces with a bit of experimentation. Obviously, I am a novice
programmer. I'm curious why you recommend quotes, is it just to make it
explicit that the values are strings?
thanks,
