The only person I can think of that could help is DickBaldwin! Maybe he could help you figure out why it won't work! Best of Luck!

Also really need to know the error message you received!

If you are getting an "index out of bounds" message or something similar, the key event is terminating a loop before it completes - something that will crash Alice. Search for comments in the forum and in Dick Baldwins notes on event whiles and similar terms for more details.
