How can I decrease my max bid?

I accidentally posted an extra zero on an auction for my max bid price.  How can I decreas that to a $20 bid...not $200?

You're in luck,correcting an incorrect bid amount is one of the very few legitimate reasons for bid retraction. After retracting your incorrect bid,you must immediately enter a bid in the correct amount.

This is the bid retraction form,which you see if you click on the link in the bid retraction page.
