Hi,
I have 2 tables, 1 for Groups and 1 for Customers, every customer is under a group, there is a Total field in the Groups table, which calculates the total for all customers under this group, with the formula:
Sum(Select(Customers[Total], [Group]=[Group Name])).
The problem is that it will only update when I edit this group row, and save again.
How can I make it update automatically?
