I'm trying to create a list picker that allows users to choose a new theme for the app based on their selection from a list. Where I am coming short is figuring out how to make it so that when, for example, "red and black" is chosen from the list picker, it runs the blocks to set the background, etc. I'm fairly new to app inventor so I'm sure I'm missing something fairly obvious but I'm stumped. Is there a way to make this happen using lists?
Thanks
