Staff switch

[Stefan Slapeta]

Hi all,

please could anybody give me a hint why staff switches are not working 
with me?? Find attached a short sample of my approach, as I understand 
from the documentation.

Thanks very much!

Stefan

\version "2.10.33"


NotesRH = {

        \clef "treble"

        \transpose c c \relative c''
        {
        }       

}


NotesLH = {

        \clef "bass"

        \transpose c c \relative c'
        {
                \change staff = RHStaff b c d e
        }
}


\score {
        <<
                \new GrandStaff <<
                        \new Staff = "RHStaff" { \skip 1 * 10 }
                        \new Staff = "LHStaff" { \skip 1 * 10 }
                >>
                        \context Staff = RHStaff \new Voice \NotesRH
                        \context Staff = LHStaff \new Voice \NotesLH
        >>
}
