Hi,

I need to have a small calculation on an Odoo website.
Cause there is no function in the standard blocks I tried to use "embed code".
I am not a specialist for such code an was asking online and ChatGPT ;-)
Here is a proposal that does not work:

(why is the /code not working??? now I replaced all brakets by "..")

..div class="container mt-5"..
  ..h1..Value Calculation without JavaScript or Scripts../h1..
  ..form method="post"..
    ..div class="form-group"..
      ..label for="inputValue"..Enter a value:../label..
      ..input type="number" class="form-control" name="inputValue" id="inputValue" placeholder="Enter value"..
    ../div..
    ..button type="submit" class="btn btn-primary" name="submit"..Calculate../button..
  ../form..
  ..div class="mt-3"..
    {% if request and request.httprequest.method == 'POST' %}
      {% set input_value = request.httprequest.form.get('inputValue') | float %}
      {% set result = input_value * 0.18 %}
      ..p..The 18% value is: {{ "%.2f" | format(result) }}../p..
    {% endif %}
  ../div..
../div..

However, the part between {...} is show like a standard text - not used to calculate and show the result.
Does anyone know how to do that?

Requirements:
Input field for the customer /site user.
Button to start calculation (a fixed percentage of the input)
Result showing to the customer / site user

Any help appreciated. Thanks.
