Need Help Creating an iTunes AppleScript

Question

Long story short: I keep my video files on an AirDisk, and when I sync my iPhone with my laptop when I'm away from home, the files are listed as dead tracks with the ( ! ) icon next to them. The simplest way I've figured to relink them is to select the video in iTunes and choose Get Info. I'd like to automate the process and am trying to write an AppleScript using parts of other scripts, but it isn't working. Here's what I've got so far:
{code}
tell application "iTunes" to activate
if selection is not {} then
set sel to selection
repeat with this_track in selection
tell application "System Events"
tell application process "iTunes"
tell menu bar 1
click menu bar item "Get Info"
tell application "System Events"
tell process "iTunes"
click button "OK" of window 1
end tell
end tell
end tell
end tell
end tell
end repeat
else
display dialog "Select some tracks first..." buttons {"Cancel"} default button 1 with icon 2 giving up after 15
end if
{/code}

Answer 1

tell application "iTunes"
activate -- Set 'iTunes' as front most application.
set sel to selection
if sel is not {} then -- If selection exists, continue.
repeat with this_track in sel -- Cycle through the selection.
tell application "System Events" to tell process "iTunes" -- Focus GUI actions on front most window of 'iTunes'.
keystroke "i" using command down -- Selects 'File, Get Info' menu item.
delay 0.1 -- Optional, user defined delay, in seconds.
keystroke return -- Clicks the defaults ('OK') button of front most window.
end tell
end repeat
else -- No track selected, present a dialog box.
display dialog "Select some tracks first..." buttons {"Cancel"} default button 1 with icon 2 giving up after 15
end if
end tell
