Summarize a field across multiple rows of a single row portal...
I have a list view with single row portal contains information from a large table. I have set each row to be the most current status of an ambulance as of a date_time at the top of the screen. Each row has a calculation that based on the status returns a 1 or a 0. I would like to count or summarize this data to get a count of ones an zeros for the entire page. I've tried a a calculation in the parent table to sum the child table values, but it returns the sum of all of the 1/0 for that unit, not the list. Is there a way to summarize a field across multiple rows?
