These two statements are incompatible:
Field('status', 'list:string'),
....
db.buckslips.status.requires = IS_IN_SET(...., multiple=False)
If status is a list of strings you must allow multiple elements in the
list. So:
Field('status', 'string'),
....
db.buckslips.status.requires = IS_IN_SET(...., multiple=False)
or
Field('status', 'list:string'),
....
db.buckslips.status.requires = IS_IN_SET(...., multiple=True)
