The Solution Rating System

With so many solutions, how can you tell which solutions are most likely to help you and which ones are not? To provide you with a tool to use, we rate our solutions based on various elements that most accurately determine if a solution is a quality solution. To explain what factors affect the solution rating, here are the elements we take into consideration when formulating our solution rating.

The Grade of the Solution
The Zone Rank of the Expert Providing the Solution
The Number of Author and Expert Comments
The Number of Experts Contributing
The Feedback of the Community

Your Input Matters
Because of the way the system is set up, the most important variable in this equation is you. As a member of Experts Exchange, you are able to cast your vote on the quality of the solutions in regard to how complete, accurate, helpful and easy to understand each solution is. When you provide your feedback, each rating is adjusted accordingly. So, if you see a solution that has a poor rating that you think is a good solution, let us know by rating it. As you do, the rating will be adjusted and will become more accurate for other members of our site.

If you have any suggestions that you would like to make for our rating system, please ask a question in the Suggestions Zone of Community Support.

Thank you!

Simple Google Distance Calculation giving error

Here's my code, simple enough:

google.load('maps', '2');
var gdir2;
var gdir37;

var gdir225;
function load() {
if (GBrowserIsCompatible()) {
gdir2 = new google.maps.Directions();
google.maps.Event.addListener(gdir2, 'load', handleLoad);
gdir2.load('from: 413 Old Ithaca Road Horseheads NY 14845 to: 79 Spencer Rd,Candor,NY 13743', {getSteps: true});

gdir37 = new google.maps.Directions();
google.maps.Event.addListener(gdir37, 'load', handleLoad);
gdir37.load('from: 413 Old Ithaca Road Horseheads NY 14845 to: 305 Grant Ave 1,Endicott,NY 13760', {getSteps: true});

gdir140.load('from: 413 Old Ithaca Road Horseheads NY 14845 to: RT 23 ,Norwich,NY 13815', {getSteps: true});

}

function handleLoad(){
document.getElementById('2').innerHTML=gdir2.getDistance().html;
document.getElementById('37').innerHTML=gdir37.getDistance().html;

Done!

It runs fine and updates all DIVs w/ accurate distances, but the Browser consistently gives a gdir140.getDistance().html is null or not an object error on line 38, which is the " document.getElementById('225').innerHTML=gdir225.getDistance().html;" line in my handleLoad function.

In the end, this is all to be a hidden function in between when a user types in an address and sees a list of addresses sorted by distance (nearest to farthest). My plan is to put the distance data in a temporary dB table (probably named using the SessionID) and then load it to the "Results" page from the dB (very, very easy). I know I could use a client-side array or something like that, but my way will work, too...I just gotta solve this Javascript error thing first.
