[Orbit]

Im just learning how to make programes in xcode using applescript studio.
For my first project I'm trying to make a small simple itunes remote. It works all good so far teh play/pause, back and foward buttons all work but im having a little trouble getting the slider to work to controll the itunes volume.
I tryed this script i created:

on action theObject
tell application "iTunes"

--set snd to current itunes volume
set snd to sound volume as integer

--set the slider to the current itunes volume: snd
set "volumeslider" to snd

--set volumevalue to whatever the user sets the slider to
set volumevalue to contents of slider "volumeslider" as integer

-- set itunes volume to what the user sets it to
set sound volume to volumevalue
end tell
end action


but it dosent work
Can someone please help me out
