Hello Jadyn, I made this demo for you because I can see the class you want to register for in the drop down. I wanted to make sure you and I were talking apples to apples as far as navigation goes.
If this is the procedure you followed and it is still not in your drop down then I will send you a link to the application here: http://www.americandanceinstitute.com/shoreline-trial-class/
1.Navigate to the Hip Hop Class Page
2. Scroll down the page and click the Winter Spring Schedule Box at the arrow.
3. Scroll down the Shoreline column in red and click the Free Trial Button at the arrow.
4. Click Choose you class
5. See your class in blue highlight.
