Post Nuke how to acces a knob on the top node

Hi,
I have this gizmo that reads maps an output them,also is going to be at the top of the chain all the time. My problem it is when I want to read a knob value from this node; lets say foo, so I can get the value and set it to another node, that its way down on the chain. The name is variable too, so I cant use:
value myGizmo.foo

There is a way to get the top node?

there is a TCL command called "topnode", which gives back the topmost node of the input chain.

Code:
[value [topnode].foo]
