Hi List, Thanks to you, I am now able to validate whether the quantities ordered are multiples of the master carton of each product. Now I am trying to figure how to have excel estimate the volume of the order, for freight quotation purposes, and that is where things get really hairy... My first idea was to create an imaginary "pile" using the width and lenght of the largest carton (they vary, as you can see in columns D, E and F), and multiply these two numbers by the sum of all heights. In the formula to show the supposed volume, I used the expressions $D$3 and $E$3 for width and lenght; then, after deleting all the products that were not ordered, I used Sort/ column D to have the largest width at $D$3 (too bad it does not necessarily corresponds to the largest lenght, but you cannot have it all. Perhaps one can tell excel to compare the values in a column and pick the largest, but this seems stratospheric for me...). In the example below, the volume informed at the bottom of column F is dumb, because I failed to consider the number of boxes ordered for each product. Column G (an attempt to take the failure above into consideration) must/ needs/ has to be also wrong, because I know from experience that this cargo does not measure 40CbM (that's 1412,5 cubic feet)! Any hint at what I should do, or where to look for an education on this? (this is my respectful way to tell you guys that I do not expect the answer in a platter - I know neither excel nor any program "think"; they carry the instructions the thinker tells them to do. my thinking capacity however seems rather primitive so far...).
