Nah, just kidding. I do have a math question, though. I need to figure out a formula for excel. I've had one running quite some time, but I did a little fiddling with it today and noticed under certain conditions, the output is screwed up... So can any calc gurus help me out if you have a minute...? I will call them by column letter for simplicity's sake. Right now, the formula reads: (N*M)+(P*O)-(C*L)=? Looks pretty simple, right? Well it's not with all elements involved. N, P, and C are unit prices that can vary. M, O, and L are unit quantities (always equal or less than D, not in the formula). L should always be the sum of O and M, and eventually equal D (not included in formula). Sometimes O and P are ~0~ and M is simply equal to D, making L and M equal. Sometimes M is less than D, but the values for O and P are not yet received (which makes thier and L's values ~0~), and a calculation needs to be made. The result is then incorrect. I know some of the data is redundant, like D and L, but this is to allow an external script to read the sheet and compare those numbers to determine first, second, or final sale.
