I must have had a typo because this now works great.
(code for anyone else that has this same qustion)
----------Working Code------------
for item in list:
fields.append(Field(item,requires=IS_INT_IN_RANGE
(0,100,error_message=('Must be an Int 0 to 100'))))
for item in list2:
fields.append(Field(item))
form=SQLFORM.factory(*[fields[num] for num in range(len(fields))])
----------Working Code------------
Validates and I can break my lists up by the requires. Exactly what I
needed.
