Multiple links with the same name on a page

I need help to differentiate between multiple links with the same name on a page in Selenium IDE. I need to click on the third link on the page. Selenium IDE records it as a reference with session ID and timestamp:

selenium.click("//a[@href='http://[blah-blah-blah]3D&time_stamp=1178132536869']");

This line does not work when I try to re-run the test.

What would you recommend to use in this situation?
