Yes, so Craig, a couple things. One, we need to -- as you're aware, we need to continue to manage the dependability of the stores business. This is something that ought to be a little bit more in our control. You know, we did have some impact of ability to get some systems booked to be able to recognize revenue, but still, the drop is bigger than the causes from the lack of bookings, which actually will fall into this quarter. It's more about operational issues. How do we make sure that we say on track delivering the tools, the -- to the customers on time? So that's one that's really operational issues for us to manage. And in the Sample Management, again, we think the bookings and the order patterns are still strong. The variability in that business comes from things that are associated with alliance on the genomics side of that business, the non-GENEWIZ stuff, the things that we run for Rutgers, and our ability to get samples registered and manage the ins and outs of the customer requests on that business. So that, for us, feels strong from a backlog standpoint. That's just we see -- we saw something a little bit unusual in this particular quarter, but still, the sample counts are coming in. The growth in that business is generally good. It's the peripheral portions of that that are different from the bio-storage sample management, but rather the touches that we have on those samples and the peripheral things related to the alliance revenue and transport, if you will, that kept us from having as robust a growth rate. So, again, things that are better for us to manage, some of the issues associated with the sample counts. As long as we continue to win sample business and continue to register them, over the long term, that will be a good, steady growth business for us.
