Place a control button in the worksheet that calls a VBA macro that processes the following

sales data $($your final code should work with data sheets that have more or fewer regions and

more or fewer months of data$).$ Write your code so that it runs on the active worksheet.

Where "Month" is in cell A$3$ and in cell A$1$ is your name. Using cell A$3$ as an anchor cell, code

the following tasks in VB $($Do NOT use For Next Loops$)$:

Find out the number of regions with data

Find out the number of months with data

Format the header $($Region $1,...,$ Region $4)$ so that they are horizontally centered, have

green background, bold, italic and black text.

Add the word "Total" two columns after the last region in the data and on the same row

of the header row. Center the text horizontally and make the background yellow, bold,

italic and blue color.

Using R$1$C$1$ notation place a formulas under the header "Total" with the sum of the sales

in the regions for each of the months in the data.

Format the numbers for the total using the NumberFormat $="0"$ property for a range.

Use an input box to ask for the number of months in the moving average of total sales.

Get the response to the input box in a string variable and check for a numeric value. If it

is not a numeric value, show a message box and stop the program.
