Ah, no, that imports values  - if I click it I get a  new 'tooth' on the node and I can connect some additional input to it. I know how to use that. What I'm wondering is if there is a way to check what the node actually got. For example, if I started with a vector-constant, did a series of operations on it- multiply - invert etc- and then plugged it in to the node as you describe, is there a way to check what is the resulting number that arrived in the node?
