#5: This line is not running properly in Chrome. I believe it is because "input" is a protected word and cannot be an ID. Were you able to text this?
#6: "plainText" appears to be a new variable. Make sure to use "var" to declare it!
#14: What if adding the key puts you beyond the end of the alpha string? This line could be problematic.

---- Things are a little bit hard to read here because of irregular indentation. Make sure to take a second look at that next time.
