Can't get an armature to respond.

Hey guys, so I’m pretty new to the game engine. I’ve made a character that worked before, but now I can’t seem to get a new one running. I’ve made my actions, set up the sensors and actuators (and connected everything), but when I press the key, nothing happens. I made sure to set it up exactly the same as the other armature, but I just can’t get it to work. Can anyone help?

Thanks!

Can anyone help?
Difficult for anyone to be able to help if they can only use telepathy or their imagination if they want to know your scene and logic setup look like

I figured it out. It was a modifier stacking issue. Thanks for the responses!

A mirror modifier might be the culprit. It will show animation in the editor but not in the BGE.
