set instead property still doesn't work

[Albert Einstein]

I can't compile:

\score{\notes\relative c'{
 \bar "|:"
 c d e f |
 g g g2
 % Initialize first ending
 \set Score.repeatCommands = #'((volta "1."))
 f4 g e2 |
 d1
 % End the first ending, start the second ending.
 \set Score.repeatCommands = #'((volta #f) end-repeat (volta "2."))
 f4 e f2 |
 g1 \bar "||"
 % End the second ending, start the "Fine" ending.
 \set Score.VoltaBracket \override #'font-style = #'large
 \set Score.repeatCommands = #'((volta #f) end-repeat (volta "Fine"))
 f4 e d2 |
 c1 \bar "|."
 % End the "Fine" ending.
 \set Score.repeatCommands = #'((volta #f))
 a'4 g a b |
 c b a g |
 f e d2 |
 c1_#'(lines "D.C." "al Fine") \bar "||"
}
}
