I'd like to create a Task when the Status of a Product is changed specifically from "Offline" to "Online". I cannot figure out how to set this workflow. I tried setting to to trigger anytime the Status field is changed to "Online", with the condition that the Status is "Offline", of course this results in nothing. 

I need to way to define that the workflow should be triggered when the Status is modified FROM the value "Offline" TO the value "Online". 

Please help!
