Basically what I was saying is that there is no place to repeat back to. When you are heading through the phrase you come to the 1st ending. After the first ending you should repeat back to the beginning, which is symbolized by a double bar line (It is the exact same thing as what ends the 1st ending, just flipped around). Without that double bar line there, you technically can't repeat back to where you stated. That's just what I wanted to point out. If it still doesn't make sense, I'll post some pictures, just let me know if you need them.
After "re-viewing" your guide once again, I found somewhat of a small liking. You did better the second time around, but I'm still going to have my rate low. If you plan on being a User Educator I'd advice having your guide perfected before even putting it into a thread. You did do a decent job, 5/10.
