Issus with sending data from additional fields using Webflow Logic to MailChimp API

Hey guys,

I am currently integrating and automating MailChimp into my site using Logic to send data through to Mailchimp using an API. So far I have managed to successfully set everything up to send the email address of the applicant to Mailchimp via the submission form on my website but I cannot seem to figure out how to also send additional data, specifically the applicant’s first and last name. I anyone could help or advice me on this issue it would be greatly appreciated.
