Simple script to name a spot color Die Line ?

[Amybeth M. ACI G7]

var docRef = app.documents.add(DocumentColorSpace.CMYK);

var spotName = "CreateSpotSwatch";

// Create CMYKColor
var cmykColor = new CMYKColor();
cmykColor.cyan = 0;
cmykColor.magenta = 100;
cmykColor.yellow = 0;
cmykColor.black = 0;

// Create Spot
var spot = docRef.spots.add();
spot.color = cmykColor;
spot.colorType = ColorModel.SPOT;
spot.name = Die_Line;

// Create new SpotColor using Spot created above and apply a 50% tint
var spotColor = new SpotColor();
spotColor.tint = 50; // 50% tint
spotColor.spot = spot;

// Apply the tinted spot swatch to a new path item
var pathRef = docRef.pathItems.rectangle (400, 200, 200, 100, false);
pathRef.filled = true;
pathRef.fillColor = spotColor;
pathRef.stroked = true;

Not sure what i am doing wrong? it makes the spot color but its called spot color?

wrong script this is what i have so far

var docRef = app.activeDocument;

var spotName = "CreateSpotSwatch";

// Create CMYKColor
var cmykColor = new CMYKColor();
cmykColor.cyan = 0;
cmykColor.magenta = 100;
cmykColor.yellow = 0;
cmykColor.black = 0;

// Create Spot
var spot = docRef.spots.add();
spot.color = cmykColor;
spot.colorType = ColorModel.SPOT;
swatch.name = "STICKERCUT";

You seem to use a variable »swatch« that you did not define previously instead of »spot«. 

[Charu Rajput · Accepted solution]

As specified by @c.pfaffenbichler , swatch variable in the following line never declared or created.

swatch.name = "STICKERCUT";

Corrrect version of the script is

var docRef = app.activeDocument;

var spotName = "CreateSpotSwatch";

// Create CMYKColor
var cmykColor = new CMYKColor();
cmykColor.cyan = 0;
cmykColor.magenta = 100;
cmykColor.yellow = 0;
cmykColor.black = 0;

// Create Spot
var spot = docRef.spots.add();
spot.color = cmykColor;
spot.colorType = ColorModel.SPOT;
spot.name = "STICKERCUT";
