The problem resides in the fact that the operation you apply is not the same when the character is >= 14 or = 14) ->18 - 14 = 4 but 18 + 14 = 32 = 26+6 and 6!= 4 • 13 ( 13 + 14 = 27 which is out of bounds. The approach is not correct, you should make the value wrap over the alphabet array and this can be done easily with the% operator: newIndex = (oldIndex+shift)% alphabetLength Without using the proper tools every a simple task becomes error prone and difficult to maintain.

You could also do it without modulo but calculations should be correct, adding and subtracting 14 to the alphabet index surely doesn't create a valid mapping. Adobe Flash Player 9 Nokia 5800.
