Of course one does not use "arithmetic". You still don't understand what is going on here, but I am now at an airport during a break in a long flight so won't be able to educated you how it is really done (and why your fix "works") just yet. But if you ask nicely, maybe in the future ;-) Andrzej Kozlowski
