Yeah, great question. We have some of our locations around the world where they were heavy services -- their business model is heavy on services in the past. They actually have a one-to-one services attach rate. So for every $1 of subscription, they do $1 of services. We have one of our licensee partners that it's more than 1:1. So we think there's still room for services to grow. What drives that there is, a couple of things. One, the nature of the problems we're helping clients solve. Oftentimes, they want us, to help them solve those. So if we're coming in and engaging a group of more senior leaders, that L&D person who might be comfortable and happy to rollout to first level leaders in the organization, they want a trusted Franklin Covey consultant to come in and work at the higher levels in the company. Or if we're taking on topics around some sensitive culture issues that are important to be addressed at the executive level, they're looking for our folks to come in, who've been there done that many, many times and who can challenge and push appropriately. Another thing that's driving that is actually, I think we're benefiting from -- frankly, from the pandemic in this area, where services sales dropped off significantly in the first quarter or two of the pandemic, because they were all booked as live in person. And our clients, even though we had the capability to do live online, our clients weren't ready, and so they just kind of froze and canceled. As we've converted our clients to live online, we've seen services increase, and I think that's a function of the fact that you used to have to go away and clear your schedule for a day or two to go to training. And now you can fit 90-minute live online modules into the scenes of your workday and your work week. And organizations who are, working remote or hybrid, they need ways to convene groups of people together, to keep that team interaction high and to keep the culture of their team intact. And so as live online, I think, is here to stay, I think that has been a real boon to our services business. And of course, clients also are asking us to start coming back in, in person, and we have that as well that our whole business used to be built on that. And so we get to benefit from both sides of that as a kind of a happy -- not that anything about the pandemic was happy, I don't want to say that, but it kind of is as an outcome of what happened with the pandemic.
