@MLClark I tried to read the article but it says I need permission to view the file.
Google doesn't always make it easy to know if the permissions have been changed. Do the links work now? If not, I'll resend the links generated when I changed permissions by another route.
This link *should* work, no matter what - but no rush with the reading! It's the kind of thing one might want to sit with for a little while, and reflect on at leisure.
