Hey there! Judging by your HTML, the form was not processed by the build:
You need to have a netlify or data-netlify=true attribute in your HTML <form …> definition. Note that once the form is processed during deploy, the resulting HTML that we serve will NOT have that parameter in it anymore!
Double-check that you’re syntactically correct and you have parity between your HTML and JS forms. If all else fails, try renaming the form and getting it working with one simple field, before expanding
