Same old, same old......Grrrr

It is now 9.15 and I have managed to get online on booking day - hooray.....

But, I have tried several times within my 10 minutes  to get a booking and every time I get a message saying '888 8889 is not valid for scroll position'.    and it won't accept my booking.  What is going on?   It was supposed to be easier this year and by the time I get online again I don't hold much hope of getting my one required booking.
