In this case let* isn't necessary. let is used to define local variables
while let* is used to create local variables in sequence (e.g. when you
need to use a just defined local variable inside a subsequent local
variable). this should do it:
#(define (compound-time grob one two divone divtwo)
(let ((hmoveDivOne
(if (equal? divone "16")
0.6
0.0))
(hmoveDivTwo
(if (equal? divtwo "16")
0.6
0.0))
(hmoveLastCol
(if (equal? divtwo "16")
-0.6
-0.3)))
(interpret-markup
(ly:grob-layout grob)
'(((baseline-skip . 2)
(word-space . 1.5)
(font-family . number)))
(markup
#:line ( #:column ((#:translate (cons hmoveDivOne 0) one) divone)
#:lower 1 (#:translate (cons hmoveDivOne 0) "+")
(#:translate (cons hmoveLastCol 0)
#:column ((#:translate (cons hmoveDivTwo 0)
two) divtwo)))))))
Cheers,
Pedro
