Good morning Naama,
I hope you don’t mine, but I fixed (and saved) the code on your page. I kept a copy of the original code just in case you prefer that code instead. 
A few things:
-
You had two onReady() functions. That’s a no-no.
-
const doesn’t work on variables that change, so I changed to let
-
I changed another line of code to change ` to ’
I tested it on a cloned version of your site and I actually got an email from it. I did get an error message regarding an error on the dataset saving some fields. You’ll have to investigate that.
I hope this helps.
Yisrael
