Description

Drift is the chatbot we are using on Merative.com. We are going to begin using the Fast Lane Playbook on our main contact us form - merative.com/contact. In order to use this playbook custom js needs to be added to the form on the contact us page. Without this javascript we will not be able to use this playbook
