If you are getting an XML error referencing a certain field that is preventing your lease from importing to Blue Moon, you will have to edit the referenced field to meet the Blue Moon requirements.
For instance, if you receive an XML error stating a zip code field does not meet Blue Moon requirements, this means the format has been entered incorrectly (too many characters or incorrect characters) which is preventing the lease from importing. The zip code would need to be corrected in your property management software before re-attempting to import the lease to Blue Moon.
