Scheme: return 10 if a function returns true

I'm trying to implement a part where if my separate function 'write?' (which returns true or false) returns true, I want it to return the number 10. 

(define value 
  (lambda (p gs) 
    (cond 
     ((write? p gs) #t)
     10 
     else 0)))

I know this is not correct because I'm getting errors, but this is the skeleton of it. I wanted it to do if write? with those parameters returns true, then have value return 10. If not, return 0.

Thank you.
