You cannot create a tag that begins with TREE_. All tags that begin with TREE_ are reserved for use by LabVIEW. If the tag you wire to the method begins with TREE_, LabVIEW prepends an underscore (_) to create a valid tag for the item. If the tag you wire to the method begins or ends with white space, LabVIEW removes the white space.
