Helios F-16 Gauges and Bindings - can't get them working.

[GPatricks]

Watched a (two year old on the F-18) YT video on setting up Gauge bindings and I believe I'm doing it properly, but not one of my displayed gauges are moving... so I must be missing something. I have the MFDs displayed and they work flawlessly. I drag\drop the gauge on my screen (i'll use the AoA gauge as an example). With the AoA gauge selected (green box), I go to the Action Window, then down to the "DCS F-16C_50" section under "Interfaces", find AoA. Under it there is one selection, "AoA Value changed" I drag that over to the Bindings Window and drop it on the "set angle of attack" listing and it shows as "to trigger value when AoA Value on DCS F-16C_50 changes". If I click that the Properties window populates but I have no clue if I should touch that. I've enclosed a pic of the Profile screen, hopefully someone can tell me where i'm going wrong.. ?
