I need some help with triggering a specific macro upon opening a spreadsheet i.e. the macro sends out an email if the data is outdated in a specific range on the sheet.
I have the "basic" email portion set up in the macro, but have FRIED my brain looking thru this data on the web site looking for guidance on how to trigger the macro as soon as the sheet is opened.
I know enough to know that I could be dangerous to myself with out help.
