How to handle moveStopped?

[Michael]

 I am moving an object to the ponts of a curved graphic. If I read the 
docs right, a moveStopped message is sent to the object moved upon 
completion of the move.
 I have put the following into the script of the graphic being moved:
on moveStopped
if grc"red" is within the rect of btn mike fitz"rube" then beep
end moveStopped

The move completes and ...no beep.

Any ideas?
