You have on Sheet2 two columns. In column A is the last name of customers (and in column B his or her first name). Column C has the last date he or she had business with you. These dates range over a year. Write a sub that will create in Sheet3 an alphabetically ordered (by last name) a list of customers who had not contacted you in the last 90 days from the current date. To do this problem, you can use the fact that you can subtarct two dates to get the number of days between them and the function date() in VBA provides the current date. /// The data in excel is not set it is whatever you want it to be.
