Sure. So, I think the best way to kind of break this down, Kim, is let's break it down in two things. In our definition, there's three pieces. First, there's leads. And leads are interest that comes into the Company that is generated from this DTC. We have seen a significant increase in the amount of leads coming into the Company. So, there's a great deal of interest in seeing the product, and by the way, actually getting one of these non-firing PDKs. So, that is up dramatically. The actual referrals that our sales force is putting together and sending into the building is also up dramatically. Our issue today, and the only reason, like I said, if you kind of think about the guidance we originally had, it was 40 to 45, and we're down slightly from that, is, we thought, it would be easier to move those referrals into, basically, finished business, in other words, billable business, that we could get it through the managed care. And we had a couple of different ways of doing that. I would tell you that the referrals and the sales force has scaled much faster than we anticipated, so the bottleneck lies not so much with the managed care company, but within this building. And while we continue to battle through that, there's a significant amount of paperwork. You have to go through the process. You have to go through those steps. And that is what we're struggling with. I would've told you at the beginning of the year, we thought we could outsource some of this to take the pressure, so we really didn't scale up quickly. And we thought the process of outsourcing that would be in terms of a few weeks, we could get these outside resources to get onto our contracts. It now appears, unfortunately, that it takes more like months than weeks for that to happen. So, we underestimated the time that we could bring up some of these outside resources, so what it has forced us to do is go back in, and we're starting to build out the internal department. So, from a demand standpoint, kind of give you some sense, I mean, we're converting, kind of number in, percentage wise, has a 6 in front of it, and we were hoping more like a 7 or 8 in front of it. Okay? So, that will give you some sense of how big the demand is and that the problem basically lies in here. And like I said, based on our experience today, it really kind of came to fruition in the second quarter because we really thought we had a solution only to find out that what we thought would take weeks is probably going to take three or four months to get some of this stuff offloaded. We just didn't think it would be prudent to go forward without taking it down slightly.
