LogixPro Bottle Line Sim

Alright, Heres my problem. I am on exercise 3 boxing the broken bottles. I am able to get the broken bottles to drop and grind, now my problem lies with the boxes overflowing and removing/bringing in a new box. I can only get the box to move until the LS is no longer true.

Here is a picture of my logic thus far.

Use a counter having preset value of 10 controlled by LS8. When approximately 10 bottles are grounded and dropped into the box, the box is filled. Now Run the scrap conveyor to push another empty box in place. It can be done by using another counter with preset value of 2 controlled by LS10.

So the DONE BITS of both counters can be used to run the scrap conveyor.
