I apologise if my explanation wasn't that clear. But you were correct in you "guess workbook".
Enter figures in $-column than make a calculation in Cent/Kg with the amount from Cell P19 (in my example wb). And then, if we should enter a number in Cent/KG we should do the opposite, and then calculate back to the $-column.
Because we have different targets in the company. Some requires e.g. a target of 6 Cent/KG, and then to do the forecast/budget we calculated back using the expected production amounts.
I hope this clarified it up.
And thank you for the code! It works how I would like it two.. I might tweak it a bit later to better suit the final workbook.
Best regards
