Problems with the animation character double jump

Hi, I need for help, i am new in Unreal4 and I am unable to make the transition to my second animation by double jump, I managed to double jump throung the tutorials, now the problem is, how can I run another animation when the double jump is precionado:

In the eventh graph i pulled the node “cast” and I pulled the value that I had in my graph of the blueprints event(through my variable Cont) assigning this value to the variable Boolean “DOUBLE JUMP”

In new, state machine, I pulled a from looping arrow to a new state “Double jump” and transition of the two, put the Double jump is true then executes the result;
But is not working, someone please help ?
