Hi Nanci. You definitely weren't disqualified. If that happens, I always contact the person to let them know (and give them time to re-submit). It appears something just happened when you submitted, which is very disappointing.
As Jan said, a common mistake is to hit the preview button, but then forget to actually go back and submit the entry. It happens to even some of our "old timers" every now and then.
I'm really sorry you missed out. It's always so disappointing when that happens. When you enter again, just send me a quick private message here on the boards to check and see if your entry made it safely into the list. Send me the Level you entered and the title, and I'll check for you.
