What version are you running on? The reason I ask is John E. Jasinski has a point about using the "Send when" = "Record inserted or updated" option and the condition fields. Makes it easy, and in this case, you should be able to use it, BUT, depends on the version you are running. The "Send when" option was added in Berlin (I think). Plus, in order to use the field comparison feature that you will need, you need to be running at least Calgary.
So, if you are, there is an existing OOC notification called "Incident commented" you could use as a starting point or modify. There's actually 2 of them, one that goes out to the Assigned to and Watchlist users and the other to the Caller. Choose the right one, and you can modify the Conditions field by adding the highlighted part below:
Now, with all that being said, sometimes you do actually have to use some scripting. And it is considered "existing functionality". Not doing anything wrong - there's a script field there for us to use in these cases. So if you must use a script, this should work for you:
if (current.sys_updated_by == current.caller_id.user_name ) {
answer = true;
}
Like Tony Fugere, William Sun and Subhajit Das mentioned above, you need to return "true" or set "answer = true" in the script. And remember, both the "Conditions" and "Advanced conditions" fields must return "true" for the notification to go out. And, if you are testing yourself with your own tickets, the "Send to event creator" field would have to the selected for the email to go out (on the "Who will receive" tab or section, advanced view of the form).
OK, I'm done
