Using date field min: option with variable gives error

Kirby 3
1

I want to set the minimum (second) date to be newer than the first entered date.

When I use min: {{ page.firstdate }} in the second date’s definition, Kirby Panel throws an error.
Question:

  • Am i doing it wrong or
  • Is it not possible with using min: ?
  • If not possible, how can I implement it?

My screen as it should be:

You would have to put the query string in quotes

 min: "{{ page.reikieerste }}"

But the query doesn’t make sense, because there is seemingly no field called reikieerste on the page level. You probably mean to get the value of the first field in the same block, but that would not work, because the blueprint is evaluated on the server side and you would need a listener on the client side.

Thank you for the answer.
I will start to learn how to create a listener on the client side.
