How to add a counter ( total number of products ) on the shopping bag in the upper right corner of the website? How to code that?

@Arup Adhikari‚Äč I'm not a developer, but checked with my team. You may use this control <vtex.cmc:AmountItemsInCart/> (https://goo.gl/iuWKZW). There's also the posibility of searching this information in the orderForm: https://github.com/vtex/vtex.js/tree/master/docs/checkout
