Hi Yaroslav,

Mathematica doesn't treat Subscript[x, a] as a symbol. There are
various ways to get around this. If you'd like for every SubscriptBox
to be interpreted like a symbol, then you could try my
SubscriptSymbols package, which is available at
http://andrew.j.moylan.googlepages.com/mathematica. Be sure to read
the warning there about auto-generated package files in Mathematica 6.

Andrew
