to be exact. "By stepping on HTML, we create a predetermined form data and POST the data to the coordinator."

I have reproduced the data of the form that I set up for the coordinator in advance, but I wonder if the form has changed.I don't know if I stopped accepting POST from outside, but it seems that the function is no longer working.
It seems that it is necessary to analyze your form screen again and create the form while referring to the parameters and items you need.

Accepting unexpected POST is one of the vulnerabilities. It's called CSRF and it's basically a countermeasure, so it might be difficult to POST from outside may be difficult.

If you look at the body part of HTML at the link, you will see the form and the script (program code) part.

At the beginning of the script section

<script src="http://coffeescript.org/extras/coffee-script.js"></script>
<script type="text/coffeescript">

The following code is written in the language coffeeScript.

The code defines two methods, collect_weekends and submit, and invokes the submit method at the end (line "submit()"

If you want to use it around, please study coffeeScript first.If you know JavaScript, it's not hard to understand.

Once you have learned the basics of coffeeScript, it is not difficult to understand the code in the script and change it to your liking.
