actually that does help. one thing I am having trouble finding though would be values for custom fields of type SelectCustomFieldRef. with the getCustomizationId, I can find the field for the SelectCustomFieldRef but I do not know what options are underneath it (if that makes sense)
like I may have a custom field of "Destination" and within that custom field a user can select "New York", "London", "Dublin", etc. Seems like I can get the field returned for "Destination" but I am not finding the fields to be able to actually set that field to "New York"
