Ok, sorry. Then try this one, this should do it…

let checkedBoxes = []
let checkBoxAmount = 1 //here you can set the amount/number of accessible CheckBox-Values

$w.onReady(function() {
    $w('Checkbox').onChange((event) => {console.log(event.target.id)   
         const index = checkedBoxes.indexOf(event.target.id);
 
         if (index === -1) {console.log("Item not existing yet")
             if(checkedBoxes.length<checkBoxAmount) { 
                checkedBoxes.push(event.target.id)
             }
             else{$w('#'+event.target.id).checked = false;}
         }
         else{console.log("Item already existing")
            checkedBoxes.splice(index, 1)
         }
     });
});
