Hi all, surely a simply one... but how do I have a field on a layout with a portal to line items that provides a calculated count of how many records (contacts) are added to a portal list.
I'm using a portal to make lists as guest lists. It would be good to have an automatic count of how many people are on a list. Here is the popover script I'm using..
I imagine I need a SUM calculation but it's just implementing it.
