Thanks everyone, I am officially back on track and the chain is in place again!!! Yippee!
I must admit, probably a bit like after some of you exchanged and had a flat feeling and started worrying, I woke up in the early hours and panicked about most aspects of the purchase!! Now it feels like it has suddenly got a bit more real, I had a little wobble.
All good though now it has all been agreed, I have spoken to my seller and she is delighted too. Phew!
