Ric Hi, Ric, I had one do that, but I had a roundabout circular reference that caused it. It just kept reiterating until it ran out of memory. Check the column formulae and see where they point to. Mine somehow escaped the detection algorithm, and I had to figure it out, but since I had created it, I knew where to look. If the formula is one you need, you can set the triggerlevel on iterations so that once the changes fall below a certain point, the iterative call stops and returns the last value calculated.
