Dataflow not working. I seen it before my very eyes.

Hi, I have another puzzle.
 
I have a VI with different levels of sub VI.  I am passing a Visa Resource down to lower levels in a cluster.
 
When I run the VI the Com3 which I send down to the lower VI  doesn't make it there until after an error occurs.
 
Looking at the code running with Execution highlighting turned on and various probes I see the Visa Resource getting passed down but  in the lower VI the resource from an unbundle comes out before the data gets into that VI.  How can data come out of an unbundle before the unbundle has its input data?

Oops.
 
Sorry for this post.  I have just been shown why.  Christian Altenbach has just ponted out that I had placed a VI directly on top of another VI and that messed things up.
