I am very new to filemaker. I just want to calculate the number of days base on the date fields.
For example, I have a client A comes to the clinic on date : may-10-2016 and then this client comes to follow up on
date June-10-2016 as first follow up after that he comes again on date July 10-2016 and he comes again on date Aug - 10 -2016. so it is 3 months followed-up.
How Can I calculate this base on the follow up date to show that 3 months completed ?
