using vyond animations in storyline

Hi, i am using vyond animations in a storyline course.  The learner picks a character and then I want to add animations with that character to follow learner through the course.  I have set up the variable for character selection but is there any other way to get this to work other than using states? 

This is an example of what I am talking about. The character the learner chose at the start  is the character that shows up in all the animations.  https://tralxd2.s3.eu-west-2.amazonaws.com/story.html  which I got here:
