T__T need help in scheme

[fullmetal]

I am new to scheme, and are learning it using Dr.Scheme, please help

I came across this question, but have some trouble with it:
A clock structure (define-struct Clock(hours minutes seconds)). Make a function that Consume a Clock structure and output the total seconds

;;this is what i did
(define-struct Clock (hours minutes seconds))

(define Clock1(make-Clock 10 10 10))

(define (ChangeIntoSec ClockX)
(+ (+ (* (Clock-hours Clock1) 3600)
(* (Clock-minutes Clock1) 60))
(Clock-seconds Clock1)))

;;end
did I do it right? because is the user suppose to type in the hours, minutes and seconds themself in the interactive window? In my answer I made a clock myself, instead of asking the user to type in the time for the clock structure

please help

thanks in advance

The logic is right.
you don't need to go into nesting here.
this will work too
(+ (* (Clock-hours Clock1) 3600) (* (Clock-minutes Clock1) 60) (Clock-seconds Clock1))

Not sure what you meant by user interface.
