I tried this as below, but it still had the same error message.
And when I used "computeInterestIncrement" like online example, it still 
had the same error message.
(define (gnc:futureValueR a t)
     (if (> t 0)
         (round (* (+ 1 ratePublic) (gnc:futureValueR a (- t 1))))
         a
      )
)
