Fixed it!

I finally figured out why the Validation(null) error occurs and have submitted the fix to the App Store!
A couple of other things I fixed:
1. When you have selected an item for a daily log entry, and then go back to the list, it now scrolls to that spot in the list.
2. When you start typing to perform a search, the search results will appear immediately. If this feature is too slow on your device, you can turn it off in the settings
3. The bonus points for values plus were off.
