Geronimo, you are correct for the numbers.
From the WT: Drag all the mosses into the tub, once all the correct numbers are entered in the boxes.
A way to tell if you have the correct numbers in the moss items, is to right click once you dipped a number of times, and click the moss again.
If any of them appear, you have the wrong number input into the moss that is showing.
Hope this can be of some help.
