Binding beta (thrust reverse) and fiel cuttoff to Saitek TA

[Granite]

Hi all. Apologies if this has been raised before however:

I have 2 x Saitek TQ's. I have mapped the throttle and CL to the appropriate axes. All good so far.

The question now is this:

I want to map beta (reverse) for engines 1 and 2 to the corresponding buttons below the throttle axes and the fuel cutoff  to the buttons below the CL. The Saitek has a detent to pull the lever into which activates a button function.

Any help appreciated. (and I am not that savvy with FWL scripts )
