modify$2.$html should include a form that prompts the user for their age,

and also for the age that they plan to retire., then submits these

to modify$2.$php for processing. modify$2.$html already contains most

of this code but needs code to prompt for the year the user plans to retire.

modify$2.$php should: receive the age and ageToRetire from the $$\_$POST array;;

calculate the number of years until they retire

based on the user's age and the age that the user plans to retire;

display their age and years to retire.
