JS: Measuring distances and areas - Not working locally

Question

The script, provided by ESRI at http://www.arcgis.com/home/item.html?id=72a44473515a4c3da8289c66a1769aba, is a wonderful one.
I loaded the script and tried to run at my local unit. The drawing looks fine. However, unlike the demo there that the results display on the right panel, no result displays in my operation. I checked the function getAreaAndLength(geometry) { }. I suspected that it could be caused by the variables wmresults, utmresults and spresults, which are defined specifically. I wish the author can explain this Q, and provide the proper answer. Thanks.

This is the continuation of my last post with the addition of the 2 images that show the Results.

Thanks for your 2 responses.  I installed and run FireBug.  I run this script again.  Sometimes, I can get the results display on the right panel, sometimes display only the Web Mercator's result, but in most of the time (> 80%), no results display.  I viewed the code (Line 69-109), I guess it could be server- or serivice-related.  The catched images are in next post.

You may also want to check out the Measurement Widget. This widget was released at version 2.3 of the ArcGIS API for JavaScript and allows you to measure area and lengths. Here's a link to a sample showing how to use the widget:
