Im trying to calculate my total inventory
So in sheet one im downloading my amazon report in sheet 2 i have all my SKU's and In sheet 3 i have my daily operation Meaning in column 1 im entering every time witch item SKU i add in column 2 im entering the date i add it to my inventory in column 3 im adding the amount of quantity i added at this time
So now i want to calculate in sheet 2 in column 2 the total inventory i have on hand by minusing all sold on the report i downloaded now and adding all i add in daily process since the last day i updated my file (So im thinking about a VBA code that should take the number already in the cell in column 2 in sheet 2 and add all added items from this SKU in sheet 3 that was added after the last time i updated my file and minus it by the inventory sold on the report in sheet 1 and then it should put in some cell on the top the date and time it was last updated so every time the code is ruining it should look in the daily process for activity witch is after the day of the last update)
