Change cell to CLOSED when Date entered

[Gauntsghost]

Hi helpful people,

I need a script that changes a cell to say closed (uses a drop box) when a date is entered into the date column. I have attached a workbook with the basic options, obviously there will be a lot more columns and information in the original workbook and I will adding the code to at least 2 worksheets.

However to give a basic understanding if I have a drop box in column A with the options Active, Inactive and Closed. When I enter a date in Column B (headed Closed Date) I want Column A to change the option to Closed automatically.

Thanks
