@centrox,
Thanks, centrox.
The three original posts were sent at about 5.25. The three 'Please help' posts were sent almost simultaneously at about 9,25 (about 3 1/2 hours after the original posts were sent out.) So when you told me on the post to wait for others to reply, the other two 'Please help' posts were already in. Hence it would appear that I wrote 'Please help' even after your advice, which is not the case.
