Hi Roelof, I'd recommend using an editor that supports rainbow brackets so you can easily see when your parens are matched.
Also, when you get your parens matched you'll find another error in your code, check out the docs for if <http://clojuredocs.org/clojure_core/clojure.core/if>to figure that one out.
