Good morning, Chris. Let me give you some color on the guide. We have a number of initiatives in the back half that are incremental to the front half. It gives us a lot of confidence that we will deliver the full-year results in our range. Let me talk sales first, and for sure, you already called it out, but, the one and the two-year stacks, obviously we’re looking at that, we do think it’s relevant to look at the three-year stack, given what happened in the back half of 2017. So, for sure, we expect an acceleration in those two-year stacks in the back half. We indicated earlier that our pro and DIY e-com businesses are performing well. They have been building momentum throughout the year on both the one and two-year stack basis. And we expect that to continue. In addition, DIY was the big challenge in the second quarter. And we’ve got a number of new tools in our toolbox for DIY that are incremental to the back half, including Speed Perks 2.0, which we’re really excited about, and improved customer experience for in-store pickup and the launch of the online store within a store at Walmart. So, given these initiatives, along with what we’re seeing as an improved demand environment that we’re already seeing in DIY, we expect to see that improve as well in the background. Secondly, in terms of gross margin, as you know, we’ve been aggressively going after DC optimization, we’re going to have some benefit for that in the back half of the year, we expect to leverage supply chain in the back half. We’ve also got managing the cost increases associated with commodities and tariffs very closely; we’re watching that very closely. But, the gross margin line obviously will have some differences, particularly because of supply chain. And then, in terms of SG&A, while we’re continuing to in initiatives that will help unlock our long-term margin expansion, we do have some things that we’ll benefit from in the back half that are incremental. We’ve got a new labor management tool rolling out in our stores, you’ll see reduced rent and occupancy costs due to our ongoing footprint optimization and continued momentum on safety. So, the net of it is as we look at our stats on sales, we expect to build momentum there. And that combined with additional productivity, particularly in SG&A is going to position us to be well within our guidance for the year.
