I'm guessing that you don't have Andale Mono installed on your computer. You may like to try Lucida which is very similar and is available on most users computers.
This highlights an issue where less common fonts may not show up on websites as they are displayed around the world. A user has to have such a font installed to display exactly. There are workarounds and you can simply add the font family to the list of fonts and it will work with the nearest available font on a users computer.
