First of all, what was the nature of the objection? The use of the word, that, was unclear. If my interpretation that you were objecting to the use of multiple, equivalent hooks - with the same priority - was correct, then I'm effectively posing the question, "why doesn't the tooling reflect the underlying philosophy?" If my interpretation was incorrect, then my post can be disregarded. However, I would still be none the wiser as to what you were instructing Slavko not to do. -- Kerin Millar
