How to use a return value from AppleScript in Hud?

I have a keyboard shortcut to run an AppleScript action and show a hud response.
The AppleScript returns a string, but how can I include that in the HUD Detail Text ?

Many thanks,

Oh, I see.

tell application "BetterTouchTool"
	set_string_variable "stars" to stars shared_secret "secret"
end tell
