Write a function that prints a loan amortization table (principal, interest rate, and number of months) are provided via form elements. The principal amount and interest rate should be entered through a text box. However, the number of months should be entered through a drop down list containing the values 12, 24, 36, 48, and 60. A button to perform the calculation should be created, and the inputs should be grouped in a field set. When the button is pressed, a HTML <div> element should be updated to hold the table.
