Dynamic Dropdown Menu using 'switch' Javascript Not Working

[Dave Moon]

Hello everyone! I have this script at the document level (simplified):

function SetFieldValues(){
var TAMCN = this.getField("TAMCN");
var Model = this.getField("Model");
var Armor = this.getField("Armor");
var Winch = this.getField("Winch");
var Reduce = this.getField("Reduce");
var DFCS = this.getField("DFCS");
var Test1 = this.getField("Test1");
var Test2 = this.getField("Test2");

if(event.willCommit)
{
switch(event.value) {

case "015305676":
	TAMCN.value = "D00037K";
	Model.value = "AMK23";
	Armor.value = "YES";
	Winch.value = "NO";
	Reduce.value = "NO";
	DFCS.value = "NO";
	Test1.setItems[("Not Applicable")];
	Test2.setItems[("-", "Serviceable", "Unserviceable")];
	break;
default:
	TAMCN.value = "";
	Model.value = "";
    Armor.value = "";
    Winch.value = "";
    Reduce.value = "";
    DFCS.value = "";
	break;
  }  
 }
}

This event is kicked off by the Custom Keystroke:

if( event.willCommit )
{
   if(event.value == "-")
     this.resetForm(["TAMCN","Model","Armor","Winch","Reduce","DFCS"]);
   else
     SetFieldValues(event.value)
}

However, my "Test" fields are not populating the setItems.  

I tried this code:

function SetFieldValues(){
var TAMCN = this.getField("TAMCN");
var Model = this.getField("Model");
var Armor = this.getField("Armor");
var Winch = this.getField("Winch");
var Reduce = this.getField("Reduce");
var DFCS = this.getField("DFCS");

const ArmorArray = [field='Test1', field='Test2'];
var ArmorArray;

var CheckOptionsY = {
    Yes: [
        ["-"],
        ["Serviceable"],
        ["Unserviceable"]
    ],
};
var CheckOptionsN = {No: [
        ["Not Applicable"]
    ]  
};

if(event.willCommit)
{
switch(event.value) {

case "015305676":
	TAMCN.value = "D00037K";
	Model.value = "AMK23";
	Armor.value = "YES";
	Winch.value = "NO";
	Reduce.value = "NO";
	DFCS.value = "NO";
	ArmorArray.setItems[(CheckOptionsY)];
	break;

default:
	TAMCN.value = "";
	Model.value = "";
    Armor.value = "";
    Winch.value = "";
    Reduce.value = "";
    DFCS.value = "";
	break;
}}

However, it doesn't set the items list at all on my "Test" dropdowns. 

Any insights are greatly appreciated!

To set Items first use round brackets then squared ones like this:

Test1.setItems(["Not Applicable"]);

OMG! ...brackets... It worked perfectly.
