Wondered if any of you have been in this situation?

I have entred Leeds Champ show with my dog and have realised that after the show this weekend she is now out of Novice...

I entred online so I can prove when I entered etc how do I stand will I have to move up to Open?

Many thanks

It depends when she won her way out of novice. The date which you count your awards to is 7 days before paper entries close. If she won the 3rd first after the 7 days then you would still be able to go in Novice at that show.
If she won her way out of novice before the 7 day cut off then you might be lucky if you contact the printer/secretary now. If you leave it until the day you would have to go into Open.
