Hi, I'm looking for a formula that can be used to automate sending out a reminder based on a certain date for every X number of years. For example, I have an "invoice due" date column, and then a column next to it saying "number of years." That number of years can be every (1) year, every year for two years, every year for three years, etc.
If I wanted to insert a formula saying send reminder when invoice due column reaches that date, as well as for two years after, how would I go about that, if the number of years column is different for each row?
