Getting Clojure to run (lein repl)

I'm just trying to get Clojure set up. Here is some code that I am trying to run in lein repl:

(def numbers (into [] (range 0 100)))
(sum numbers)

But I get this error:

CompilerException java.lang.RuntimeException: Unable to resolve symbol: sum in this context, compiling:(NO_SOURCE_PATH:1:1)

I don't know what this means. Is my installation wrong?

I'm not sure which sum function you're trying to call, but you can use reduce:

user=> (def numbers (into [] (range 0 100)))
#'user/numbers
user=> (reduce + numbers)
99
