Hello again :)

I have a problem with the code below, lilypond gives me errors with
the two scheme expressions.

 \version "2.18.0"

 correctionAlignement = ##t
 aligner = \relative c' { g'4. g8 c,4( c) | }
 lyrics = \lyricmode { Glo -- ri -- a __ }

 <<
   \new Staff <<
     \new Voice = "melodie" \relative c'{ \voiceOne g'4. g8 c,2 | | }
     \new Voice = "alto" \relative c' { \voiceTwo c4 bes c2 | }
     #(cond ((eq? correctionAlignement #t)
       (#{ \new NullVoice = "aligner" \aligner #})))
   >>
   #(if (eq? correctionAlignement #t)
     (#{ \new Lyrics \lyricsto "aligner" $lyrics #})
     (#{ \new Lyrics \lyricsto "melodie" $lyrics #}))
 >>

Can someone tell me why ?
Thanks in advance ! :)
