Learjet,
Here's what I have for you, I think you need to change the channel assignments. Click on the transmitter and copy it if you have not already done so, then click edit. This should bring you up to this image. This is the channel assignment selection. On my transmitter screen the throttle hold switch was channel 6 or second from the bottom and it says throttle hold switch in the blue channel name section. on that same line, move left to the very first column where it says source and then click on the axis on the same line as the throttle hold. Your task is to figure out which axis on the transmitter is throttle hold. I don't think you need to change the Input type where it says Controller axis, but probably the next field down. as you can tell from this image my DX6 controller has the throttle hold on Axis 4.
Give it a try and see what happens, let me know.
