Lucy, there is probably a limit to the number of params although no-one seems to have stumbled on it yet ;-) However, passing twelve (!!) seems a bit out. Surely you can massage the data into a local record and pass that. It makes for easier and more flexible code. Personally, i am trying to go for only 2 params maximum, except for toolbox calls which don't let us decide. jonathan
