Need help mapping motion controller trigger axis values to an animation

So I’m trying to make it to so depending on how hard you depress the Vive controller’s triggers, the hands will close accordingly. Below is my animation blueprint and my Blend Space 1D. I’m just not sure how I’m supposed to use the float that comes from the TriggerAxis in my Character Blueprint and use it with my animation blueprint/blend space. Some help with this would be greatly appreciated.
