AppleScript won't compile (?)

[Richard Gaskin]

Pasted below is an AppleScript I found at 
<http://www.apple.com/applescript/quicktime/> to obtain info about 
chapter tracks in movies.

While I can paste it and run it fine in AppleScript Editor, putting it 
into a field and using:

   do fld 1 as AppleScript

...generates an error: "compiler error" (not very helpful)

So my question is:

    What could be causing the script to run well in AppleScript
    Editor but not using Rev's "do" command?

TIA -
