Hey I think you got a bit confused? I´m not sure what you´re trying to do but you don´t need to edit that code for normal use.
do like this:
1. Make sure you have the thickbox plugin installed.
2. Via FTP open the 3 files related to thickbox in your text editor, they are:
www.danielarsham.com/ndxz-studio/site/js/jquery.thickbox.js
www.danielarsham.com/ndxz-studio/site/js/jquery.js
www.danielarsham.com/ndxz-studio/site/css/jquery.thickbox.css
3. Go to http://wobbleweb.net/wobblebox/jquery.thickbox.js copy the code, and use it to replace your own jquery.thickbox.js
4.Go to http://code.jquery.com/jquery-1.4.2.min.js copy the code, and use it to replace your own jquery.js
5.Go to http://wobbleweb.net/wobblebox/jquery.thickbox.css copy the code, and use it to replace your own jquery.thickbox.css
6. Save all files back to the server
7. Good to go.
