Showing linked data's

Hello, 

I've got a table with various lease contracts. Each lease contract is linked to one or more owners. If there is more than one owner, I would like to get the name of the owners linked to one lease contract. So, if A and B are linked to the same contract, I would like to get the name of B on the record of A and vice versa. 

If I use the formulas proposed, I get all the names linked. 

Thanks already ofr your help

Best regards,
