Hi Laurie,
I think your script is currently living in both worlds by having both "executeRule" and "onBefore" functions defined.
I believe checking the Execute Function box tells the system to look for a function called "onBefore" and automatically run that. With that box checked, you can just start your script the old way with...
function onBefore(current, previous) {
If your script starts the new way with...
(function executeRule(current, previous /*null when async*/) {
...then the Execute Function box is not necessary because you have a self-executing function: once all conditions are met, the system will automatically run the code inside of that opening parenthesis.
Your options should be:
1) Check the Execute Function box, then remove all of the "executeRule" stuff and start with "function onBefore" in your Script.
2) Un-check the Execute Function box, then start your code immediately within the "executeRule" function (meaning your second line would be "gs.addInfoMessage..." in this case).
The second option is the new standard, so you may want to try un-checking the box, then deleting the "function onBefore" line (as well as its closing curly brace below). Good luck!
