if/else ifとリストを使用しているAppleScript

Question

私は学校での再生のためにスクリプトを操作するスクリプトを作成しています。問題は、私はそれがifステートメントを通過することができないということです。それは変数selectedOptionを設定しますが、一度それがifsとそれ以外の場合はそれを飛ばしているように見えます。

--repeat 
activate 
set myOption to {"Start Play", "Scene 1", "Between Scenes", "Scene 2", "Next Song", "End Play"} 
set selectedOption to {choose from list myOption} 
---------End Play--------- 
if selectedOption is "End Play" then 
    tell application "iTunes" 
     set currentvolume to the sound volume 
     if (player state is playing) then 
      -- if so, fade out the current track 
      repeat with i from currentvolume to 0 by -2 
       set the sound volume to i 
       delay 0.1 
      end repeat 
      stop 
     end if 
    end tell 
    display dialog "Volume Back Up?" buttons {"Full", "80", "End"} default button "Full" 
    if the selectedOption is "Full" then 
     tell application "iTunes" 
      set sound volume to 100 
     end tell 
    else if the selectedOption is "80" then

    ---------Scene 1---------
