One of the legs of the LED (can't tell from the pic) on row 24 doesn't go anywhere... Might be your problem...

No luck with that.
I realized I also had the little orange jumper connecting the battery + directly to the LED + which I corrected in the latest file uploaded.
Please take a look - this one I think is correct across the board and it is not working at all (no LED light or anything).
:(
I am about to take the breadboard completely apart to sketch this out.
Does anyone have any thoughts?
Thanks!
