This retailer is also interested in understanding the business potentials of its local markets. He collected the sales volume in the local markets across 11 different categories from Jan 2012 to Sep 2013, as shown in the worksheet Sales DataLookup". He hopes you to develop a simple tool using Excel which he can use to look up the sales volume given a specific category and a given month. That is, in the worksheet SalesDataLookup" of "Exercise 2" workbook, cell B17 and B18 are the areas he can input any specified category and month. Please develop the lookup tool in cell B19 of the "Sales DataLookup" tab of "Exercise 2" workbook. Do not worry if B19 says #N/A if B17 and B18 are empty, we will only be grading B19.

If your formula in cell B19 is correct, given an input of category and month in B17 and B18, the value returned in cell B19 should be exactly the same as the corresponding cell in the sales data area.
