The form is shown as a redirect from an Unbounce page. The unbounce page should pass a URL parameter, which will be detected by the script from DialogTech and do the rest.
Any help is appreciated.
You can insert custom scripts in your form when you use your form source code.
Here's how to get your form source code http://www.jotform.com/help/104-How-to-Download-a-Source-Code-of-your-Form.
FYI, embedding scripts in the form builder is not possible, they are stripped for security reasons.
