Thankyou
Well she has struggled with this one for ages, so i gave her a months break and tried a new tactic...
I got her in a Sit, then a Down, then with a very tasty treat in my hand moved it from her head down her side to her leg, so her head should naturally follow the treat, gravity takes over and she rolls onto her back (this is when you say Roll Over). Move the treat accross her body so its at the other side, she should then get up and she can have the treat
