Some Input axes not working

Hey guys, I am having a problem with some of my GetAxis inputs not working. Here is my script: void Update() { float b = Input.GetAxis("Submit"); if (b > 0) { Debug.Log("h"); } }

whenever I press the enter key, not$$anonymous$$ng happens in the console. Is anyone else having t$$anonymous$$s issue? It also seems to be happening inconsistently with some of the other axes. I made sure enter was set as my positive button for Submit, even reset to the defaults. It was working fine until yesterday, I've restarted Unity a couple times.
