Can someone please help with this poofer script? :)

I got this poofer script from this message board. Thank you to the writer of it. Can someone please fix it so that it will work for anyone? Right now it only works for the owner. I would really appreciate that help.
Thank you!

Hellboy - 'Particle Poofers' are usually objects that you attach to your own AV. For this reason, whoever has it attached should always be the owner anyway. (You can't attach an object you don't own)

I'm guessing you're not using it this way. What are you trying to do with this thing, so we can understand better what you want it to be able to do?

Travis is right. But if you dare to let everybody be able to perform, change the following line.

From
llListen( commandchannel, "", llGetOwner(), "" );

To
llListen( commandchannel, "", NULL_KEY, "" );

But all messages still recieve to the owner because they speaks by "llOwnerSay". You might need change it to llSay or llWhisper.

Thank you very much.
The reason I was wanting it to set for anyone is so when I make one to sell I can have a demo version that others can try out.
I really appreciate the help.

Please correct me if I am wrong, but your plan is to take a FREE public script that you got from the forums, modify a few variable settings, and then close the script and actually sell it?
Please tell me that I am wrong, and you are just using this script as a reference as you actually create a script of your own accord. Otherwise you are really just selling a freebie, and it will have no real value whatsoever.

I guess the selling point of this product is the effect with his original texture, not this script itself.
