Viewing different records
Is there a trigger or something that happens when I view a different record?
For example, I have a record that is a list of items, all with a cost. For each record, I want to see a total for all the items. The costs change in each record.
The question is, if use the arrows at the top to go to a different record, the total doesn't update. Is there a trigger that happens when you change to a different record? Am I thinking about this correctly?
