Gus,
I just joined this group, and I do have an excel sheet which is fairly complex as it does throwouts which turns out to be a challenge in excel.
I have a slightly different view to Frank - am I allowed to disagree with an advanced member?
- I would never rely solely on a computer lakeside, but I have found it to be a great way to cross check the poster/whiteboard.
Let me know if you want a copy
