One of your responders said 'database learning get's easier all the time'. Well, true - but slowly. I actually debugged something that I found by accident. Where there's a will, there's a way.
I have a blank item is my database (Item 2). Can't get rid of it. I synched SANDBOX to LIVE (Sandbox doesn't show the blank item but LIVE does) ... no joy. I tried synching the other way and I can't delete it at all. Not a biggee- just an annoyance. Both are set to read/write.
