After the show of the file in the web page, after the change of a value in one cell the browser gets busy and return this message : https://.... /zssapp/zkau/web/4e814308/js/zk.wpd:5479 is busy or don't return any, please select the option: 1) continue with the script 2) stop the running of the script.

The problem is the same also if I delete the formulas in the two columns.
