Need Help with getting a form to work

The form is located here:

https://clancy.sugarondemand.com/cache/generated_forms/WebToLeadForm_1338568620.html

I am trying to put that form into a a wordpress page.

I tried pasting the JS into the page and the form failed to load.

I tried pasting the javascript into the header and the form worked, but I don’t want that javascript to load on every page.

What is the best way to do this?
