Help with an exercise.

Alright I'm doing exercise 11. in chapter 6 of the alice book. Im trying to get it so that when the word gato is clicked the cat says "Si, Si!" and when its not clicked the cat should shake it's head left and right. It's basically just like the zeus exercise but for some reason mine isn't working.

I'm not sure what I'm doing wrong so somone please help me out here.
