Thanks FoxLee2...I didn't know that there was a change...not that it would have helped. I'm finding this page a real challenge.

That was briliant swannbaker...thanks. Googled Oaks winners and there were all my answers. Pleased to say I only had to change 2 of mine. Wasn't convinced about Toboggan, but there it was.
