Write a sub that requests a positive integer with an InputBox. Then use a For loop to sum up all the odd integers up to the input number [e. g. if the user enters 8, the program should add up 1, 3, 5, and 7 only]. Display the sum in a message box. Once you get this part working, delete the message box, and change the sub so that it enters all the odd numbers in consecutive cells in Column A of the worksheet, starting with cell A1, and displays the sum, boldfaced, just below the last odd integer.
