Passing filenames from LaunchBar to KM-Macro

Cool! Thank you Peter. With a little help from http://www.obdev.at/resources/launchbar/help/RunningAppleScripts.html i created this:

on handle_string(theString)
   tell application "Keyboard Maestro Engine"
	make variable with properties {name:"Input Parameter", value:theString}
	do script "Process Parameter"
   end tell
end handle_string

And it works! Thanks again!
