Well it's "sort of" in there, but not really highlighted. If you update every second with a step size of 60, then you can feed in one value of 60 and 59 values of 0 - and get the result of 1/second for the step. Min. Max, etc only come in when consolidating PDPs. That's what I've observed anyway. -- Simon Hobson Visit http://www.magpiesnestpublishing.co.uk/ for books by acclaimed author Gladys Hobson.
