Pass argument to function

[Brandon Booth]

I'm trying to learn Chicken and having issues. I'm trying to create a function that takes a docker container name and runs "docker inspect [container]."

This works:

(define test (capture "docker inspect hello-world"))

This works:

(define (str-concat str)
    (string-append "docker inspect " str))

This doesn't:

(define (inspect str)
    (capture (string-append "docker inspect " str)))

I get an error that string-append is not found. How do a call capture with the result of string-append?

Thanks.
