Nick,
That worked perfectly. Thank you!
One more question. I'm now having some difficulty importing my
'author' property because it says it needs to be a user. I get
BadValueError: Property author must be a User. However, if I just set
it to user, I get NameError: global name 'user' is not defined
Is there a conversion function for the UserProperty as well?
Also, is there somewhere I can find these conversion functions?
Thanks,
Mike
