I am also trying to customise a Property Box Tab but appear to have found something that I can't do.
What I am trying to create is a tab showing immediate relatives of the individual.
e.g. Father, Mother, Sibling 1, Sibling 2... Child 1, Child 2...
I've tried %INDI.FAMC[1]>HUSB[1]>NAME[1]% and %INDI.~FATH[1]>NAME[1]% but FH won't accept these because:
'This data reference contains one or more links to other records. These are not permitted in this context'
Does anyone know what syntax might work?
