\mark error

[David Bobroff]

In the following Lilycode there are two instances of "\mark".  They are
generating errors:

*******
error: syntax error, unexepected DIGIT: \mark 1 (\mark 2)
*******

I can't figure this out as this is *exactly* how I've done it in two other
files which process just fine.  Here is the offending code:

\score{


        \notes \relative c, {
        \property Score.MultiMeasureRest \override #'expand-limit = #9
        \property Score.breakAlignOrder = #'(
                  instrument-name
                  left-edge
                  ambitus
                  span-bar
                  breathing-sign
                  clef
                  staff-bar
                  key
                  time-signature
                )
                \property Score.RehearsalMark \override #'molecule-callback =
   #(make-molecule-boxer 0.15 0.3 0.3 Text_item::brew_molecule)
        \clef F
        \property Score.skipBars = ##t
        \property Voice.subdivideBeams = ##t
        \time 6/8
        \key f \major
        R2.*12 %% NEEDS TEMPO MARKING!! --> Allegro vivace
        a8->-\ff r r r4 r | R2. %% NEEDS "Vuota"
        R2.*14 | f8->-\ff r r r4 r8
        \bar "||" 
        \mark 1
        R2.*12 %% NEEDS TEMPO MARKING!! --> Molto più lento
        \bar "||"
        R2.*12 %% NEEDS TEMPO MARKING!! --> Iº Tempo
        \mark 2
        R2.*9
