How to stop sounds played with "Notify - PlaySound" in AnimInstance ?

Hey guys. Can you tell me what I am doing wrong? I keep going over the what y’all said and it looks identical doesn’t it? I created a new AnimNotify blueprint > clicked override in the functions and hit notify begin and end > created an audio component variable in my character blueprint > created a sound base variable in the AnimNotify blueprint > copied what Ross90 has and added the notify state to the character animation. But I keep getting this error. It is driving me up the wall.
