See that's what puzzling. U misspelled the OP wanted 3,9,9,3,2,12. 10 was bad. Not sure about the 12... can't see that many rows. With the OP's rules as you suggest, it should be 3,9,9,3,1,1,2(that I can see). Tcnt can't be set to zero initially because there's always one row. As long as everybody's happy. Dave
