You are using the wrong url to display your test results. To use the correct one do the following:
When you log onto ORB:
1. On the left hand side under 'Logged in as....' click on 'My Results'
2. In center of page under 'My Results', click on the tab 'All Results'
3. That will present you with a drop down window to pick which set of test results you want to look at.
4. At the bottom of each individual test result you will see 'Private Result'.
5. Choose the score you want to display by clicking on 'Make Public'.
6. Now the 'Private Result' has changed to 'Public Result' with a 'Compare link:' url.
7. Copy and Paste that one.
Example of what url should look like:
