Ok, I have what should be a simple little query, that is driving me crazy. 2 Worksheets, one sheet has a list of phone numbers with dates, thats it 2 columns. This sheet only has 1 record per phone number, 100 in all. The second sheet has the same exact phone numbers on it, and dates as well, but this sheet has more than 1 record per phone number. What I need to do is find a way that on sheet 1 in col C (currently blank) tally up how many times that the phone number is listed on sheet 2 WHEN the dates on sheet 2 are >= 3 days from the date on sheet 1. Scenario - sheet 1 is a list of numbers who have a work order open and the date is the day the order was opened. sheet 2 has the same exact numbers, but the dates are the dates that the person had called into our company. I need to find out how many times a person called in within 3 days after they had a work order created for them. I have tried INDEX, MATCH, VLOOKUP, and for the life of me I cannot figure this out. PLEASE HELP!!!!
