How do I move Right & Left?

I am so close!

Ok the Phone is at 90 Degrees Landscape - As If I Am Taking A Picture of Someone In Front of Me.

Alpha, Beta, Gamma work completed different when the phone is at 90 degrees.

I can get Gamma to move the little green sprite Up and Down when I tilt the camera up & down - YAY!!

How do I get the little green sprite to move Right & Left when I turn the camera right and left?

Beta doesn't move the sprite right/left except under certain circumstances. BOO!

Some times it will, some times it's just a PITA.

And Here is my code: iticka.com/c3/motionSickness2.c3p

Please, how do I get the little green sprite to consistently move right and left when I turn right & left.

I even made a Colorful Graphic!
