To find the place where you have to add the autofill codes,
you will need to go to your layout configuration.

first, click on the "my layouts" button on the left-hand menu,
then click on the layout > page > Page Head Script. 

Check the next screenshots showing where to find it: 

- Save data code:

<script>
    $('[data-tag="emailmkt"]').on('submit',function(e){
        var objEmail = {};
        
        $($(this).find('input')).each(function(i,element){
            if($(element).attr('name') == 'EMAIL'){
                objEmail['EMAIL'] = $(element).val();
            }
            if($(element).attr('name') == 'FNAME'){
                objEmail['FNAME'] = $(element).val();
            }
        })
        localStorage.setItem('emailmkt',JSON.stringify(objEmail));
    })
​​​​​​​
</script>
