Delete "Date" field

Delete "Date" field

I tried to make a date field automatically put the days date in but it is not working so I want to delete it.

When I try to do so, an error message comes up stating that the "field is referred in . . .  Schedules." and to remove them.

I can find no way to remove from schedules to then be able to remove the present "date" field and start all over. - jb
