When you previewed that node, the website gave you a message that said:

If something looked unlike you expected it to you might need to check out Writeup Formatting Tips

Did the preview really look how you wanted it to look? The formatting of you input file is really very important if you want people to help you parse it. It would make it far easier to help you if you took the trouble to make sure that the formatting was accurate.

Or perhaps you didn't preview the node. You were in such a hurry that you pressed "create" rather than "preview". Hopefully you can now see why that's a bad idea :-)

(For anyone reading after the inevitable editor's clean-up - the node originally had no <code> tags and therefore everything ran together on one line)
