Press Key Once?

Hi so I’ve created a crouching animation but it requires me to hold down the crouch button for the character to be crouched but I want to only press the key once to crouch and then press the key once again to get up from crouching. Down below is my blueprint, what am I doing wrong?

Flip Flop is what you probably want.

My animation works just like how I wanted too! Thank you so much
