Hi. You must be new.
Welcome to rmrk!
First, it's important to read up on the rules and guidelines for each forum. For help with a script, it's always best to ask within the thread the script is given in.
Secondly, in that particular script, you'll find a demo to download that explains and shows you a lot of your options.
MA also puts most of the directions for his scripts into the top part of the script itself.
I reccomendation downloading the demo, reading through the script, and then posting any specific questions to the thread you mentioned.
Good luck and welcome again!
