I have a C# program that I cannot get to work. Seems easy:(

The application should ask the user how many days the user would like to rent a car, then display the following car rental options to the user.

Compact car for $28/day
Intermediate for $32/day
Full size for $33/day
Sports Utility Vehicle (SUV) for $44/day
Minivan for $65/day
Luxury vehicle for $89/day

After the user picks the type of rental car, the application should use the number of days and the selected price per day to calculate the rental car price before taxes.

I really need some help...
