Code Embedded into Wordpress Post

HI all! I need a simple script embedded into a wordpress page and a wordpress blog post. I can't seem to figure out how to do it without messing up the template. The website is here: [login to view URL] And the script page that needs to be embedded is here: [login to view URL] All of the files are in the appropriate directory. I am trying to set it up to where I can secure the page as unaccessable until someone has purchased a subscription to it. The script extracts information from yellowpages. My wordpress has the HiFi plugin installed, where you can inject a script before the </head> tag. Please let me know if you can modify the script to work inside of these pages. Thanks so much! :) -Connor Berge
