In general if we get users with perplexing questions it's typically due to them getting ahead of themselves w.r.t how to solve tasks, and asking the how to solve the task from a high level description is far easier to answer given the knowledge of the community.<br><br></div><div>Robert.<br></div><div> </div></div></div></div>
