Update 24th March 2024:
The certificate problem has now been fixed, and most download links should now work without a problem. Note that any file with VBA code (which is almost all of them) will have the VBA blocked with no obvious unblock option. The procedure to unblock the code is actually quite straightforward and is detailed at: https://newtonexcelbach.com/2023/04/28/two-views-on-vba/.
If there are any remaining problems, please let me know with a comment.
Original post:
It seems there is a problem with the certificate for my downloads folder, which generates security warnings if anyone tries to download anything. I am working on fixing that, but in the meantime the link below should allow download of any of the files posted here:
Please let me know if any problems downloading, or if anything is missing.

It’s okay. I have dwonloaded the file by previously click “show more options”, click “properties” and
click the “unblock” box down the bottom as you said on march 12. The file seems have worked properly.
Thanks a lot Doug. That answers my query
