hello I cannot seem to figure this problem out. Anyone know how to use listboxes with a radiobutton?

The ABC Shipping Company charges the Rates listed in the following table:

Weight of the package (in kilograms) Shipping rate per mile in California Shipping rate per mile other states 2 kg or less $2.0 $2.5 Over2 kg but not more than 6 kg $3.0 $3.5 Over 6 Kg but not more than 10 kg $3.5 $4.0 Over 10 Kg but not more than 30 Kg $4.0 $4.5 Over 30 kg $5.0 $5.5

Create an application that contains two radio buttons to select California or other states, a listbox for the user to select the packages weight class, a textbox to enter the distance it is to be shipped, and a button to calculate and display the charges on a label control when it is clicked. Input validation: Do not accept distances of less than 5 miles or more than 3000 miles
