Key binding the Comm Preset selector not recognized by X: Cockpit Argument

[Apache600]

Howdy there,
   If you bind a key to turn Comm 1 or 2 preset selector left or right (to change radio channels)   which is titled in the controls as [UHF Radio 1 (or 2) Preset Channel Increase (or Decrease]  ... as opposed to putting your mouse over it and using the middle scroll roller to change it, then the trigger function  [X: Cockpit Argument in Range]   (I'm using:  argument 300 for comm 1,  min = 0.01,  max = 0.02) is not recognized.
   The Key Bind DOES actually switch the frequencies.  So you can go from M to 1 to 2 etc.   However, if you look closely, when you using the key bind, the graphic of the selector knob does not rotate (as it would if you used your mouse scroll wheel).   This, I believe, is why the [X: Cockpit Argument] does not work, because it's not actually turning the "physical" knob on the UFC.
