* Please remember that Items lists are different than Product lists, but either way they both have the same Formula window and act exactly the same. The only difference at this point is that the items had the formula populated when you insert them into the library. 
* Also remember that this video is prior to zzTakeoff getting Volume as a built in variable and so some of the math done in here is outdated.
* Since this video creation we have made volume CY a standard equation,, so there is no need to divide by 27.
