Glide List Script for PA Breakdown Mapping

[KBoz]

We have a glide list field on Incidents for tracking the groups involved.  I would like to pick off the first value from that list and use it in a breakdown mapping.  Below is what I have so far, but not sure I am on the right track.  How do I write the script to only bring back the first value in the list?

You are close, you just need to drop the loop since you just want the first value.

(function(){
	if(current.u_glide_list_1){
		var groups = ("" + current.getValue("u_glide_list_1")).split(",");
		if(groups.length > 0){
			var gr = new GlideRecord("sys_user_group")
			if(gr.get(groups[0])){
				gs.log(gr.getValue("name"));
				return groups[0]; //This will return the sys_id of the group.
			} else {
				return "";
			}
		} else {
			return "";
		}
	} else {
		return "";
	}
})();

Thank you for the quick response!  I tried it out am getting the following error below.  Any ideas?

Error during JavaScript evaluation: Not all references of "current" are passed in by "arguments" script: (function(){
if(current.u_glide_list_1){
var groups = ("" + current.getValue("u_glide_list_1")).split(",");
if(groups.length > 0){
var gr = new GlideRecord("sys_user_group");
if(gr.get(groups[0])){
gs.log(gr.getValue("name"));
return groups[0]; //This will return the sys_id of the group.
} else {
return "";
}
} else {
return "";
}
} else {
return "";
}
})();

Nevermind.....got it to work!  Thanks for your help 😊

(function(){
if(current.u_glide_list_1){
var g = current.u_glide_list_1;

var groups = g.split(",");

if(groups.length > 0){
var gr = new GlideRecord("sys_user_group");
if(gr.get(groups[0])){
gs.log(gr.getValue("name"));
return groups[0]; //This will return the sys_id of the group.
} else {
return "";
}
} else {
return "";
}
} else {
return "";
}
})();
