I think I understand.  You are using x, y, and z literally in your code, and not
to represent some value in your post.  In that context, x, y, and z are vector
identifiers, not operands.  They would have to be enclosed in a function block
to be treated as operands.  The average method that you listed is probably the
best way to work around this.
