FCU Altitude and Heading not working with Axis and Ohs

[LukeFF]

I attempted today to map the FCU knobs for altitude and heading to a couple of encoder knobs on my controller, with the Axis and Ohs scripts I downloaded from flightsim.to a while ago and work fine for some other commands I have mapped. 

However, for these two FCU knobs, the increase and decrease buttons do not work at all. I thought maybe it was because they are encoders, but trying to map them to momentary switches didn't produce any solution - the knobs just sit there idle.

There are two different AAO scripts out there for the A300 on flightsim.to and I tried both sets of scripts, but neither of them would work.
