Hi, in the grid view, I am able to group fields and have the total count or sum of each columns. How can I apply that to calendar or gallery view?
I am operating a tour agency where I have a trip ID, date of the trip and number of participants. However, participants can register for each trip randomly on any date. How can I add the number of participants that is taking part in trip A on 1st of April for example?
Thank you in advance for helping.
