@paulkpk. Where does one start? Same problem as SamT "ooOOOOoOoOooOOO" or "All the math in your loop will end in Zeros", or snb who thinks "Variable Y seems to be discarded" or "it seems very smooth indeed", Paul_Hossler who is wanting a sample book to be provided, or the OP of this old thread?
It always amazes me that people jump unto old threads, provided very little in way of supporting information, and demand that someone replies as soon a possible. I'm assuming you have at least read this thread before posting, and from that you can reasonably see that no solution was found since those wanting to assist were waiting for the OP to supply further detail. Which brings me to the second point, since there is clearly very little supporting data why would you not provide a workbook sample to allow others to assist you. Thirdly, it would be extremely helpful if you could indicate what your own efforts so far have achieved.
