How do I get trigger input to continue working?

I am using a controller for controls and I set up the input manager with an input that is set up on 9th axis so I can get the left trigger. it has it’s gravity set to 1000, dead set to .001, and sensitivity set to 1000. I had this set up working for awhile but now it has stopped working. I have tried changing the joystick setting to all the different joy numbers but none work for getting input. I am at a lose to what might be wrong. Any ideas?

Figured it out. I have to plug the controller in after I start unity.
