I have a table that has three fields :
assetid(character), meter(0000.0), mtrdate(DateTime)

How do I base a report that will show me the elasped hours from the lowest meter reading to the highest meter reading for a specific time span?

The time span should work with:
REPORT ... FOR BETWEEN(mtrdate, {low date}, {high date})

Does anyone have any ideas on the hour meter part?

Thanks
