tst/dkfire,
Thankyou for the tip about the "to more generic class". I have tried using this in a different example and was having some problems and this would explain it.
To answer both your questions about how I could misconstrue the help file. My problem is that I didn't make the connection between the node I was dropping into the VI and the VI it was applying to. Some of this was as a result of the initial dropping of the node not working (because the parent VI's were not built and it didn't work obviously).
At the end of the day I was using the node in the block diagram of the operation VI which also had a parent DD VI so I read that as the first part of the requirements met.
I was wanting it to use the operation2 child VI which was a DD VI and had the same name as the operation2 ancestor VI I wanted to call which to me satisfied the requirements as well.
tst, you asked the retorical question "Which VI?" well to me that answer was not obvious. I figured I had satisfied all the requirements and it should therefore work.
Can I see where I went wrong? Yes.
Do I think the help needs to be changed? Sorry guys but yes I do.
All the best
David
