Variable Pecking Order

[Joe Davenport]

Hello,

I am new with LilyPond but have managed to find a way of listing variables;

guitarB =
  \relative c' { d8 e f g a b c d }

voxMelodyA =
  \relative c' ...

and inserting them as an order of phrasing under the \score staff 
grouping. Unfortunately I am having difficulties when adding lyrics! I 
receive an error message that the string " " for lyricsto cannot be 
found. Notice that I tried to create a "voxSeq" for the vocal 
arrangements before putting it inside my group of staves. Perhaps I must 
do this for the lyrics as well...

(see context below)

\score {
\new ChoirStaff <<
  \new ChordNames { r1 r1 \chordA }
  \new Staff = "Guitar"
    { \guitarIntro \guitarA \guitarB }
  \new Staff <<
    \new Voice = "allVoxMelody"
      { \voxSeq
      }

    \new Lyrics \lyricsto "voxLyric" {
      r1 \voxLyricA \voxLyricB
      }
    >>


Thank you!
