Yes Nate, one thing on the $12 million to $15 million in Q4, I would ask you not to extrapolate because those numbers fluctuate all the time, so that was the impact specifically in Q4. The impact in Q1 could be similar, it could be less, could be more, so it is always a range, so I would not extrapolate. Our projections show, or our expectation from supply chain is that we should be able to recover in the next couple of quarters, but that situation could change, so that’s a fluid situation. Your second question about cadence of margins, I indicated in my prepared remarks we expect the first half to be lower, and a number of factors come into consideration here. One, as you know, Q1 is always a low quarter from a volume perspective, and that results in lower margins. We also have the mathematical effect of Bite, so Bite we expect to decline in the first half versus last year, and so that is a headwind. Then we have some of the supply chain issues that I talked about, so that’s going to depress margins in the first half. As we go into the second half, then there are tailwinds; for example, Bite we expect to be a contributor to growth in the second half. We expect the acceleration of product launches to gain traction. We are pretty excited about the progression we are seeing with Pro Taper Ultimate, Primetaper and CEREC Tessera. Those products are gaining traction - they began in Q4 and they progressed throughout the year. Those are going to be important contributors to growth in the second half. Primeprint, although not very significant, is also another improvement in the second half. The last point I would indicate is pricing. In Q4--actually October 1 of 2021, as you know, we implemented a price increase that is going to start annualizing now, so that helps ’22 first three quarters, and then we have the opportunity and we will monitor the market and we’ll potentially do more price increases throughout 2022. The inflationary environment is real, it’s happening. Costs are going up and pricing is also something that we can use to offset some of those incremental costs, and hopefully have a net positive impact from pricing. Hopefully that helps with respect to the cadence for ’22. Beyond ’22, good question. We’ve talked about this before. I think we always--once we are at the level of 22% operating profit margin rate, for us it’s going to be really important to balance growth, top line growth with further margin expansion. I think a 22% margin rate is reasonable. Can we do more? I think we can do more, but at that point our biggest priority, our higher priority is going to be making sure that the top line starts growing faster than we have seen so far.
