I have a Gallery named GalleryPositions with items from Sharepoint list "Staffing List" I have another Gallery on same screen names GalleryCandidates with items from Sharepoint list Candidate. "Staffing List" has a column named CandidateIDs that contain the ID's of Candidate delimited by spaces. "10 34 40" I can use the following: Filter(Candidate, ID in Split(GalleryPositions.Selected.CandidateIDs, " ")) to show those Candidate list items where ID's in "Staffing List":CandidateIDs in Gallery GalleryCandidates. What I want to do is show the remaining items in the Sharepoint list Candidate. So I have a list named "Staffing List" and a list named Candidate. An item in "Staffing List" can have multiple Candidate list items attached. I want Gallery GalleryCandidates to show those list items that are attached to GalleryPosition.Selected then the remaining Candidate list items.
