Thanks Steve,

For some unknown reason it worked last night. So I made my corrections, and tonight it won't work again.

I've tried just coping the work I did today over to the disk I used yeaterday, but still no luck.

Tried three new disks so far.....

I would not know how to move things, I will just have to complete what I can and send the disk to my administrator.
She said to leave the '0' out of the RG No. But that didn't work either. I now have numerous copies and also saved to Documents folder. Don't know what to do.

Thanks anyway. I won't give up. I might just clear the lot and start again.
