State-Switch inside config-template-card doesn't work

[Veuchez]

State-Switch inside config-template-card doesn't work, I don't see anything. If I remove " ${LANG_STATE..." the card works again but I lose the functionality of config-template-card. Here is an excerpt of my code. Am I doing something wrong?

type: custom:config-template-card
variables:
  LANG_STATE: states['input_select.smarther_cucina_language'].state
entities:
  - input_select.smarther_cucina_mode
  - input_select.smarther_cucina_language
card:
  type: custom:layout-card

You mixed FOUR cards in a code which is supposed to be a Minimal Working Example.

And it's not okay? are there any limits?

[ildar170975]

Minimal Working Example - a code demonstrating an issue. If you dealt with a software development you know what is a SW testing & localizing a problem. What you posted is a complex code w/o any attempts to localize the issue.

I solved it was my coding problem. Sorry for the waste of time.
