I want to count the days between the current date and a date field. I have tried the following formula which works: 

days360(zoho.currentdate,input.Last_Swipe)

However, the day count remains the same on future days until I manually change the date in the Last_Swipe date field. How do I automate the above formula so that I do not have to manually update the Last_Swipe date field to make the day count update?

Thanks in advance for your help.
