I'm around all day.
When you copy the code to the practiceboard, use the "see HTML" button. It will display the page and will also give you a semi-permanent link to your stored page. That's what the /?####### string means.

Edit: Just saw your post on the error. That does suggest the code has a problem. Sounds like a loop error of some sort, like Javascripting would do.
