Setting up a mouse wheel to control the speed of movment

Hello,
I am following a tutorial(link below) on how to increase speed by using a mouse wheel up and down, instead of using a 3rd person character I am using a Pawn. I can get so far until I need to set up a Set Max Speed Node…it only gives me 2 options for a floating pawn or Projectile movement… is there any way I can get this to work with my set up or is there another way to set this up wit this pawn? I added two images …1 is how far I got and 2 is what it looks like in a 3rd person character
