I am having trouble writing a WA tutorial resource. The tutorial that I am writing “How to install a "Pin It" bookmarklet on the ipad. Is just about finished.
The part that I am stuck on is the code that the user needs to to insert into their bookmarks to make the "Pin It' bookmarklet work always changes wording after I save the page. Below is a screenshot of the page that I am trying to save the code on.

The word javascript always changes to the word removed, and the wording spreads into the right hand column on the page.

Below is a screenshot of this problem. The red text which is the code is my problem.
I have a work around where I link to one of my websites that contains the code, but I would prefer to keep things neat and tidy and contained in the tutorial.

I submitted a Report a Bug yesterday, but would like to finish this project this weekend.

Thanks for your help and ideas.
