Compare two multi-checkboxes

Play a little bit with console.logging …like…

$w.onReady(()=>{
    let selOptA=$w("#checkboxGroup1").selectedIndices; console.log(selOptA)
    let selOptB=$w("#checkboxGroup2").selectedIndices; console.log(selOptB)
    console.log(selOptA).length
    console.log(selOptB).length
    if(selOptA.length && selOptB.length === 6){
        $w("#button1").enable();
    }else{
        $w("#button1").disable();
    }
});

Take a look into —> CONSOLE! (Press F-12 in Google-Chrome and navigate to —> CONSOLE, or use the integrated CONSOLE of your Wix-Editor)

Now you are able to investigate your own coded CODE.
