How to remove the transactions from Google Analytics Ecommerce?

Question

I have made several test orders and they are tracked successfully by Google Analytics Ecommerce. For now, I want to remove one of the orders and I take the advice from http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=75012 , here's the snippet I composed http://gist.github.com/471505 , I saved it in a .html file and opened it with Firefox, waited for more than 24 hours, and I found the transaction is still there, it's not been removed, any idea? Thanks a lot.

Reread carefully the article from http://www.google.com/support/googleanalytics/bin/answer.py?hl=en&answer=75012, and you'll find the following note:

Note that you will still be able to see the actual transaction and the duplicate negative transaction when you select the day on which these transactions were recorded. However, when you select a date range that includes both the original and the negative transaction, the transaction will not be shown in the report. The negative item quantity should result in the same effect in the products reports.
