I'll do my best to describe what I think you mean by "File" which to me in this context is my Macdonald family tree.
FTM Macdonald tree open. People. Select Janet Scott from lefy hand pane. (appears along with her husband A J Macdonald in centre block) Invited to add Janet's father. Do so, followed by her mother. Do so. Add children, Add Janet's G/father and G/mother. In File Menu I had not previously used "Merge" and now do so (after backing up) Publish The Scott addiotions to the Macdonald file (?) still do not appear in the Genealogy Report/Register Report which is where I want them to appear. I suggest that my Scott additions have been accepted, as they appear (perfectly) in the Extended Family Chart as an extension of the Macdonald chart. If the same additions were added to the Register Report the problem would be solved. I've been as detailled as I can within the limitations of my FTM knowledge, which I may say has improved enormously under your guidance. Alistair
