Okay. I've made a model to show you what we're going to use for your project. It is much simpler than your project, so it should be easier for you to understand. And you need to understand it because otherwise if you break it you'll have no clue how to fix it. I plan to write up a tutorial for this project, but I don't want to make you waMusicDictionary.capx
Open it up and run it. You'll see the layout name (Level 1) and four circle buttons. Click on a button and it takes you to the corresponding level (level 1, level 2, level 3 or level 4.) Notice that the music changes each time you change levels.
Now look at Level Events, which is the event sheet for all of the levels. There is no code to start or stop the music.
It is all handled in the two included event sheets you see mentioned at the top. The first of the included event sheets puts the names of the layouts and the music they should play in a dictionary. This included only needs to be included in the event sheet for the first layout in your project (your phone layout.)
The second included event sheet uses the name of the current layout (LayoutName) to play music that it looks up in the dictionary. This event sheet has to be included in the event sheet for every layout that uses the dictionary to lookup and play music.
So what does this mean to you?
It helps you organize your project. It means you only have to go to one place to set the music for all of your layouts, much like the list I had you make out. And once you've included the event sheets to load the dictionary and play the music, you don't have to worry about them anymore!
Now open up MusicDictionary Events and examine it. You'll be creating a Music Dictionary action for every layout in your game. I'll create a few of them for you and you can make the rest so you'll know how to do it.
I'll also add the event sheets to a few of your layouts and you can do the rest, again so you'll know how to do it.
By the time you've read this and looked at the project I hope to have your revised project up.
