    Can somene help me create a milage script?

    I am trying to create a basic javascript that shows milage between severag areas, similar to what you find on the rear road atlas.
    I have tried and failed to create anything, i just think i am total useless at understanding javascript.

    The basic concept is this image attached.

    There would be a drop down box that lists the destinations and another with the same but would be departure.
    When a person chooses example: Butte >>> Kalipsell it would show 238 and vice versa.
    it seems a simple thing to do but cant get my head around it all.
    Could someone create a simple script, say 3 destinations and i will fill the rest in and see if i can understand what i am doing and then ask for additional help if required?

    Here's one way to do it.

    Code javascript:
    var locations = {
        'Billings': {
            'Bozeman': 143,
            'Butte': 228
        'Bozeman': {
            'Billings': 143,
            'Butte': 86
        'Butte': {
            'Billings': 228,
            'Bozeman': 86
    createLocations(locations, 'mileage');

    You might want to break down the createLocations function in to several different ones though, such as:

    Code javascript:
    function createCells(cells, type) {
    function createTable(data) {
    function createLocations(locations, target) {
