Been away a lot. Nearly done though. I'm probably going to create an extra sheet and put almost all the cr@p int it. A couple of Qs, though.

What is the MAXIMUM number of B/L's that you will have to take into account at any time?

What is the MAXIMUM number of ACTIVE (ie containing stock) stock lines in a B/L that you are likely to have? I suspect that this number will be truly horrendous!!
