Hello All
(defn chang[f key hj]
(dosync (ref-set f (assoc @f key hj))))
(defn proceed-now-right [alon key]
(let [val (extract-num alon key)
row-dev (eval (get-next-row inc (first val)))
keyword-dev-right (get-key inc (second val))
cell-empty-right (check-cell-empty? keyword-dev-right row-dev)]
(if cell-empty-right
(do (chang row-dev keyword-dev-right (@alon key)) (chang alon key
\space))
(println "can't do this"))))
I found that each time I try form proceed-now-right I get error when IF is
true. Why is it so? The function chang works on it own...
Regards,
Emeka
