LightningFX problem

I'm trying to use David M's script LightningFX as described here and modified for UDL as described here, but I can't get it to work.

I've doubled checked that i copied the modified code and replaced the correct code in the script.  When I start up th eSandbox the console reports:  "LightningFX v0.1 initialized."

The token I'm using to trigger the effect meets all the requirements of Step 1 of the Setup description from the first link above. (It's named "Lightning" [I've used just a token and also a token representing a character named "Lightning"], it's a transparent token I got from the Invisible Token thread in the Forum, there is no "All players can see light" setting in UDL, and Aura1 is set to 0 ft.)

However, when I place the call !lightening on in chat nothing occurs.  ( I tried using the example valid calls but none caused any change.)

If anyone can help, I'll really appreciate it.

Dumb idea: are you typing "!lightening" as in your post? You have an extraneous "e" in there.

I'd actually recommend trying this scriptlet written by The Aaron. The script I wrote is pretty fiddly and requires more setup. Aaron's is a musch more elegant solution imo. 

Jim R. - Not dumb since I clearly mistyped it in my post.  However, I double checked and !lightning doesn't work either.

David M. - Thanks for the reply.  I've been using TheAaron Flash script but wanted to automate things a bit more so this one from him might be the answer.
