Hey ben-hig: So, I went through the test cases for the solution, but it is using a very simple sort function: items.sort(function(a,b) {return a.priority - b.priority;}); Without trying to 'point a finger' at your code, I think there is some inconsistency with how you are dealing with sorting the items. I tried to get your solution to work by modifiying the test case sort, but that doesn't help at all. I think you may need to modify your solution to handle the sorting properly.

Thanks for bringing that up; Will have to get that fixed up!

I've aded a fourth test which should satisfy the random factor, and also will more than likely have more than 10 items output

Are we talking about example test cases or the actual test cases? If the actual test cases, the third test case has a random number of items, from 4 - 32 which would fit the multiple shipment criteria. In any case, I could always rework that last test case, or add one more that randomizes the number of assembly lines and items? Would that help?
