I looked in the database and can see that we found no form fields at all in your html form at deploy time (both of the forms on that site are the same - have no fields defined in the plain html). Please review this doc, as it describes exactly your problem and how to fix it:

Thanks for reaching out, and welcome to Netlify Forums
I am sorry you are having trouble getting your forms to work.
This Support Guide is the first port of call to debug any forms issues. There are also many other Support Guides for forms - you can find them here: #Netlify-support: support-guides
We also recommend trying to search the forums or look at topics tagged Netlify forms if you haven’t already - it’s likely your question was already asked by someone else!
If you are still having problems after reading the above links, please create a new thread and provide more information such as what you have already tried, a link to your live form, any errors or logs from your builds, etc.

I know it’s not a neccessary function, but if the dev team has free time (lol, they won’t have) it is an idea to do
