Tekken style Movement help

Hello everyone I’m trying to replicate tekkens movement of two enemies always facing each other but Being able to move in a 3d world, I got everything working except the up and down movement and I can’t figure out what I’m doing wrong. Even if I negate w and s. W will always go down and s will always go up even though it’s supposed to be vise versa. If anyone can help it would be greatly appreciated. this is the blueprint Rff - Album on Imgur
