How to enable checkboxes in Google Spreadsheet?

Question

Google Sheets

There is such a table: It is

necessary that people who have a link to it cannot edit or delete anything from the table, but can click on the checkboxes to use a simple calculator. Can you please tell me how to implement this?

Answer 1

"clicking on the checkboxes" is what edit is.
Just add the word copy to the end of the address instead of the word edit
. Or protect all columns on the worksheet except the checkboxes.
But still, only one person can work with it at a time, which kills the whole point.
