This script works on my own mac but not on a remote mac.
Remote Apple Events is on.

volume is ok and works
but itunes didn’t work:
“play” is a variable while running on remote but on my own it is the play command. why?
but stop is markt as command (blue) but it didn’t work too
quit is ok while itunes is running

if itunes is closed and i try the itunes button
nothing happens, apple script writes: iTunes got an error: Cannot find process an host.

thanks for your help

THAT:

  1. need machine (get “eppc://10.0.1.3/”) form,
  2. need using terms from application:

set rm to machine (get "eppc://10.0.1.3/")
set the eingabe to ""
repeat
	display dialog "Volume(0-7), iTunes(1-Start, 2-Ende, 3-Play, 4-Stop)" default answer the eingabe buttons {"Abbruch", "Volume", "iTunes"}
	copy the result as list to {the eingabe, the button_pressed}
	if the eingabe is not "" then exit repeat
end repeat

if button_pressed = "iTunes" then
	tell application "iTunes" of rm
		using terms from application "iTunes"
			activate
			if eingabe = "2" then
				quit
			end if
			if eingabe = "3" then
				play
			end if
			if eingabe = "4" then
				stop
			end if
		end using terms from
	end tell
end if


if button_pressed = "Volume" then
	tell application "Finder" of rm
		using terms from application "iTunes"
			if eingabe = "0" then
				set volume 0
			end if
			if eingabe = "1" then
				set volume 1
			end if
			if eingabe = "2" then
				set volume 2
			end if
			if eingabe = "3" then
				set volume 3
			end if
			if eingabe = "4" then
				set volume 4
			end if
			if eingabe = "5" then
				set volume 5
			end if
			if eingabe = "6" then
				set volume 6
			end if
			if eingabe = "7" then
				set volume 7
			end if
		end using terms from
	end tell
end if
