I am creating a report in excel and I am having some trouble returning the correct number. I need two criteria for the look up one being the date value and the second be a grade level. as an example on the start page the user inputs a date say 3/31/2008 then on the report page there is a grade level associated with a given row of information. The grade can be 1-18 and are located in cells A2:A20. There is another worksheet in the workbook that has a date in column A, a Grade level in Column B, and in column C there is a population to go along with these two criteria. Is there a formula I can use to return the number from column C?
