I want to have the action menu display a value that belongs to its part. Not a button. Anyone know how I can do that?

So I have been looking at existing mods on how to display information in the action menu. (I have little experience with mods)

The following creates a button:

[KSPEvent(guiName="Press Me", guiActive=true, active=true)]

 

What I need is to display a number, kind of how KSP can do with science parts like the Barometer in the screenshot below which shows: "Display: 100.2831 kPa"

Just need to be pointed in the right direction. Any response is appreciated.

KSPField...oh. good
