Change entity based on input number on another entity?

I’m a rookie when it comes to templates and custom configuration and lean on examples heavily with an intent to hack them to meet my needs. However, in this case, I’ve searched and searched and haven’t found an answer.

I need to display a entity in lovelace (input_number.lock_code) based on the value of another entity (input_select.code_slot).

First can this be done?!
Second, how in the heck can I make it happen?! lol

Below is an example of what I want to do…When I select the Code Slot from the drop down, I want the Lock Code to update automatically to the slot I just selected.

lock

Thanks in advance!

Look at the “conditional card”.
