We can't post spreadsheets on the forum, for security reasons, that can then be edited with new entries to get different results. It would be nice to be able to provide fully usable spreadsheets for some things like calculators, etc.
I put an Open Office spreadsheet on Google Drive, which seems to be downloadable from a link. It comes up read only, but there is a link to "Open with Google Sheets), that for me anyway made it usable.
Could a few people give this a try to see if will open, and then open in sheets to be usable? The green highlighted areas would be the areas of new data entry.
