I guess I misinterpreted the phrase "only when one of its order line has 
been added or deleted" as meaning that a change to any of the amounts would 
trigger an event. It wasn't clear to me that the example actually presented 
a calculation that would be evaluated based on that event.

You might want to give potential users a better idea of what this tool 
does. Neither your announcement nor the homepage made that clear to me.
