Clojurians Log v2

I'm extremely new to Clojure and I'm trying to follow along with the book "Web develoment with Clojure", and I'm already a little stuck in the first chapter. I am having issues running tests

The error I am getting is the following: Syntax error (FileNotFoundException) compiling at (C:\Users\endre\AppData\Local\Temp\form-init9065213963356311033.clj:1:108). Could not locate guestbook/test/db/core__init.class, guestbook/test/db/core.clj or guestbook/test/db/core.cljc on classpath.
