Scenes not referenced in build

Hello,

I have created a test for a game in Unity and everything works fine in the editor. However, when I build the project my references to my scenes are missing. I have 2 scenes and it is setup so that I can jump from one scene to the other using a button which, when clicked, calls a function from my program manager object to load the given scene. Here is a screenshot of the inspector for one of those buttons and the code I am using to load the scene:





Let me know if you can help.

 

Did you add your scenes to the build?
