How do I replicate a gamepad's axis to be the same as a pressed key?

I'm sorry if this has been answered somewhere else, but I want to be able to mirror a sprite using a gamepad joystick the same way I would by doing key presses. (for example, key pressed "Left" set mirrored, key pressed "Right" set not mirrored). How do I get the same effect using a joystick? I tried comparing the axis, but the sprite will only mirror as long as it's held down.

Try this code:

Gamepad Compare axis < -50 : Sprite set mirrored

Gamepad Compare axis > 50 : Sprite set not mirrored

That did the trick. My values just weren't high enough. Thanks a bunch!
