Cross-site lookup with SPs Person or Group column

Hi, I’ve recently started using cross-site lookup to give more power to forms and have created a cascading lookup as per the article here. I now want to find a way to use a lookup on a “Person or Group” column from another list. To explain a little using the tables in the article mentioned above: In the Countries table add a column “national rep” which uses a “Person or Group” column getting SharePoint users.
Person_or_Group.
I want to bring this info through to the Target form based on the country selected. I can get this to work if I use a single line text box in the Countries table and type the names in but not if I use a Person or Group column. Many thanks. Chris

Dear Chris,
Just like regular SharePoint lookups, Cross-site Lookup only supports certain columns and Person/Group is not one of them, unfortunately.
