Sure. So, let's start with the latter. We've had no issues with regulatory issues. We've – as you know, CarpX was [indiscernible] approximate 45 days for submission. We've been able to get our pre-submission meeting scheduled and I know others have suggested that that we haven’t experienced any delays on the regulatory front. You know, on the commercial front, I kind of expand on what I was mentioning, which is that, you know, we always, even though you know, COVID is still with us and there's still concerns about it spiking in the fall, you know, we always knew that you could, that you could only delay non-emergent procedures for so long. I mean, non-emergent procedures still need to be done. People still need to be screened for cancer. They still need to go under – undergo other procedures, which may not be deemed as an absolute emergency. And so what we have found, after pretty much a three-month hibernation, if you go sort of March, April, three to four months, March, April, May, and then much of June is that the system is waking up and that despite the fact that they're still okay, but there is still plenty of COVID. You know, even in geographies where, you know, that are that are subject to new hotspots down the south and southwest that clinical entities, hospitals, practices and otherwise are figuring out how to get back on track with necessary elective procedures. Again, I don't like the word elective, because it means – it almost implies that you can do without them and that's just not the case. And so, we have found both on the clinical trial enrollment, as well as with our engagement of clinicians on the commercial side that things are actually – are just starting to pick up in the last four to six weeks, and you know, how long they will take to get back to full steam that's obviously hard to predict, but you know, we're in the early stages with both of these and so, you know, as I mentioned from the statistics, I outlined, I mean, we're actively involved in hundreds of discussions with hundreds of accounts where, you know, we have dozens and we expect that to grow accounts with product on the shelf. And we really expect commercial procedures to start picking up any day now. Now, that things are opening up and as I noted are, as a preview of that, our clinical trial enrollment is picked up [indiscernible]. So, you know, there's still uncertainty with COVID, but, but you can't withhold these procedures forever and we expect that we will start seeing up ramp in both commercial cases and clinical trial alone.
