Your (recur ...) is completely mixed up. The specific error you are seeing is because of the subexpression: (cont (contains? ...)) which attempts to apply cont as a function to the result of the call to (contains? ...). cont isn't a function, it's a boolean value (you gave it the value false at the start of the loop). > The call=> (valueIn(sudoku vall poss) gives me the above error. > > Thank you, > -- Gary > > -- > You received this message because you are subscribed to the Google > Groups "Clojure" group. > To post to this group, send email to clojure@googlegroups.com > Note that posts from new members are moderated - please be patient with your > first post. > To unsubscribe from this group, send email to > clojure+unsubscr...@googlegroups.com > For more options, visit this group at > http://groups.google.com/group/clojure?hl=en -- You received this message because you are subscribed to the Google Groups "Clojure" group.
