Hello,

I have a business in which it's very important to calculate how many days a customer is client with us. I created a custom field in Clients with "Start datum" in which the starting date is collected. How can I create a field in Clients which displays how many days this client is a client of us. And obviously, when "End date" contains information it should count only until that date.

I have very limited coding knowledge! :)

Thank you for your time.
