This screen shot is what the finished product should look like

Write a macro and link it to a button in the worksheet CustomerTotals. Your code should work with data sheets with different number of days and stores. 1. Find the number of stores 2. Find the number of days 3. Two columns after the last store add the title name "Total Customers and three columns after the last store add the title name MA Customers 4. Calculate the total customers for each day across all stores, and put it in the "Total Customers column. 5. Take user input to decide the parameter of moving average. Repeat input until valid input is received (hint: positive and above 0) 6. Create values in moving average column - the first one should be (#+1)th row below the heading the last one should be one row below the last record, where # is the value of the moving average parameter (from step 5.) 7. (make sure to clear the MA forecast column when updating) File Home Insert Page Layout Formulas Data Review View Developer Share Comments Record Macro N Properties Help e Map Properties Import Expansion Packs Export Source col Refresh Data HI!
