Need help on circular patterns, I think

Hey everyone I'm working through the Intro to CAD curriculum about 3 days ahead of my students. It's been going super well up to now, but I'm really struggling with lesson 2.5.4, which is adding a logo to the skateboard. I've figured out several ways to make the logo in a sketch but I can never get it to be fully defined, no matter what I do. I have dimensioned everything I can think of and no matter what it never is defined. I've read other forums and from what I'm able to understand, I've done everything I'm supposed to, but nothing works. Anyone else done this lesson and worked through problems with it? I've spent about 6 hours on this problem and don't know where to turn.

Circular patterns are misleading sometimes. The center of the circular pattern isn't constrained by default. See animation below.
Thanks. I figured out that this was the problem and finally got the sketch to work. The next thing the instructions ask me to do is to use that sketch to split the part that it's on the face of. I am selecting the skateboard deck as the part to split and the face of the sketch as the entity to split with, but when I make the split, there are no new parts, which tells me that it didn't split? I've been working on this logo for almost a week now. I don't know if I've been this confused since quantum mechanics back in college!
I believe the instructions tell you to use the sketch to split the face, rather than the part. You just need to split the face of the deck using the sketch. Then you can change the colors of the faces.
I had tried that too, but to no avial. But I went back in just now and messed around with it a bit and I finally figured out what I was doing wrong. After the split, when I was selecting the split parts to change appearance, it was always picking the sketch that the split was based on, rather than an actual part of the face. I tried hiding the sketch and that was all it took.
Thanks for all the help. It's really great that Onshape has you on staff. So much of my life as a K12 teacher in a small rural school I have no one to turn to when I get stuck trying new things because I am the "expert" no matter how little I know. It's been great getting help from you on this forum and the curriculum and other resources you guys have provided are a lifesaver.
