Help!!! PS3/XBox Button Maps

Ok I am trying to map my PS3 controller buttons, which registers as a XBox controller but the R2 & L2 doesn't seem to work inside of Unity for some reason.

Here is the button map I followed:

R2 & L2 are the same as the "Triggers". I am not sure how to execute the inputs for the triggers.

Triggers = 3rd Axis (Left: -1 - 0, Right: 0 - 1) _ (Left Trigger Axis: 9th, Right Trigger Axis: 10th (Both axis are 0-1))

Can anyone point me in the right direction please & Thank you!!!
