Well, they both are set equal to "s". :-)

Yeah, it hurts my brain, too. But I've e-mailed Dr. Gonzales
a couple of times when I've been really stuck, and he is always
nice enough to explain to me where I'm going wrong. (I've even
discovered a couple of errors no one else had yet pointed
out. This could be one of them.)

Cheers,

David
