I need further help about this. The VB code you provided Richard works, but my spreadsheet is linked to other spreadsheets. So, everytime I open the file, it asks me if I want to update the content and I click yes (since it's possible it has changed). The update makes the date change, even if the value didn't change. But I don't want the date to change if the value doesn't change... I hope it's clear. If you need more details, let me know

Thanks again very much for your help!
