Uncheck a checkbox by checking a radio button, using pure javascript

Question

I'm learning pure javascript and need your help with a problem!

What I'm trying to achieve:

I want to create a checkbox. When the user clicks the checkbox I want a window to open. In the newly opened window will be multiple radio buttons. If the user clicks on one of those radio buttons, the checkbox outside of the window will uncheck and the box disappear with

Problems:

• In the code the reverse don't work.

• The connection between radio = check to checkbox = uncheck does not work.
