So, thank you, but there appears to be no way to reschedule these listings except to start all over from scratch. I made the huge error of, after repeatedly trying the click ons to the right of the in error listings, hitting the delete button instead of bringing up each one at a time and saving it. Of course, they all dissappeared. So I pressed the back button on my computer, back a page, got them to come up, tried to save each one, and alas, no saved listings. Man oh man, am I having a hard time of it. Don't know my computer type, but I guess I will try contact support.l
