Hello @sachingupta ,

Try below <script></script>.

$(document).on('ready', function () { // initialization
var counter = 0;

$.HSCore.components.HSQantityCounter.init('.js-quantity', {
stopIncrease: function() {
if (counter >= 19) return true;
},
afterIncrease: function() {
counter += 1;
},
afterDecrease: function() {
counter -= 1;
}
});
});

Thanks,
Tuecus.
