Data Activator Not Activating

Hello Mat42 . In your example, Data Activator will alert when the value of "Number" for any "Name" becomes greater than 200. This means that it will alert when the Number for a given Name was previously less than 200, and then becomes greater than 200. In your screenshots I can see that there's a value for "Jeff" in in the second chart, but I don't see a value for "Jeff" in the first chart. If "Jeff" only appeared for the first time in your second chart, then it won't trigger an alert, because the value was never less than 200. If you instead update the value of "Dave" to, say, 250, then you should get an alert.
