Multiple Closed Captions and Languages using simple Javascript

A solution without javascript could be as follows.

• Create a var "language"
• create a language selection slide that sets that var to a specific language
• on each video slide you can place the same video with different language captions on different layers and show a certain video layer depending on the chosen language (so make a condition that checks the var)
• It looks like you have duplicates of the video, but when you check your storyline publish (story_content), you will notice it will only use 1 video file for all the languages.
