I'll say that I'm impressed by those of you who have completed the Chapter 4 programming assignments. I have spent so much time reading, re-reading, browsing documents on the web, etc., and I know something still isn't clicking. I THINK I'm getting somewhere on 4.7 but it isn't working yet. Would someone mind looking at this and letting me know what you think??? If you see stupid mistakes (which I'm sure there are), please point me in the right direction!!
