Paper 2d Knockback Question

Got a paper 2d and added in a launch character when the enemy touches the char. It works perfect, except when I’m on the right side of the enemy, it still launches me -400 in the x axis. If I’m on the right side of the enemy I’ll need it to knock me +400 on the x axis. What’s the best way to ahieve this?

Here is my BP setup that works so far.
