Need help, trying to make a custom charge and hitting a few problems

So currently Ive given my custom trike a charge ability. Pretty much everything works exactly as I want it, except the actual charging animation.
I copied the running animation and converted it to a montage with a unique name. When the trike charges, it uses the walking animation.
If you hold the run button, it uses the running animation, all while charging.


Ive barely touch animations so I’m sure I’m just missing something super simple.
