Ok, so specifically what do you want help with here?

I wouldn't "laugh" at anyone who makes the effort to have a go at what are quite complex Excel formulas (ok, maybe column I...), but I should let you know that column I does contain a bunch of #REF! errors - presumably you cut some sheets/cell references before posting?

Anyway, like I said, if you could be specific about what exactly you want help with in here.

Regards
