Triggering an event with Value (signaling)

I'm trying to trigger an event using the Value(Sgnl) property. My primary VI loads and runs a second VI containing a random number generator in a loop. When the random number exceeds a constant it changes the value of a control from zero to one using the Value (signaling) property. The control is registered in the main VI using Event Dynamic registration. Please see the enclosed code.

You register the control, but there is no event case that acts on that dynamic event...

D'oh! OK, I fixed that so I have a "vi reference"; Value Change event but it still doesn't trigger. Another stupid mistake? Did you get it to work?
