I have one tab and on it I have 3 columns date, dollar Amt and margin. On another tab I have two columns one is a list of dates and next to them is the Interest rate, this second tab basically is a historical listing of the fed lending rate. I want to place a field on the first tab that looks at the date on that tab and compares to the second tab to find the rate based on where it falls in the time frame and populated it with the rate from the second tab
