How to show a different graphic depending on game variable score. So stuck!

Hi, I'm working on a story-based project to promote better time management in which the user accumulates a 'stress score' depending on answers given in each scenario (poor time management choice= more points). I have added a variable player score which works perfectly. The stress score is currently shown on the main 'home' slide which each scenario sends the user back to after completing a chosen scenario. I would like the score to change the state of a character (her face getting angrier if you've scored high) but can't for the life of me get it to work! As you can see in the photo, I've entered 'change state of character 2 to angry when the timeline starts if playerStressLevel is >=2. Yet as 2nd photo shows, no dice! :(

I've made sure the states are correct and definitely look different. 

Any suggestions?

Ps I know the project looks a little rough still, just trying to get the nuts & bolts right first!
