On the dashboard, did you use the same name as the name you wrote for the cRIO robot project for the read vi for the smart-dashboard vis? I see what Alan is talking about, the wire for the get refnum of the ultrasonic is not connected to the vis after it. The floating analog device refnum is what he is referring too, I am also confused as to why do you need that to the front panel. The answer to your question of where the vis should go for your ultrasonic is to have your get voltage and smartdashboard variable inside the periodic task loop only, everything else outside of it.
