I am trying to show selected item in a repeater with a color layover and there can be only one selection. I have put a colored box in the container hidden which shows on click but it doesn’t seems to be working.

Here is my code:

$w("#container3").onClick( (event) => {

                
   
  let $item = $w.at(event.context);
  let clickedItemData = $item("#stepone").getCurrentItem();
  console.log(clickedItemData.title)
   $item('#box43').show()

} );

Here is the link:
