Hi Guys,  Wondering if you can help me out with the following. Within a single event I have to fields:  1) expiry_date 2) delivery_date I would create a new variable giving me the difference in days between the delivery date and the expiry date for each order.  For example  expiry_date=2021-05-25T00:00:00Z delivery_date=2021-04-27T19:00:44Z Should give a result of 28days.  Hope you can help! Thanks in advance.  ... View more
