applying a swatch to a pathitem

[subieguy2]

I am trying to apply a swatch to all pathItems on a certain layer. I have the code written to access the layer I want but I am not sure how to apply a specific swatch name to the pathItems on the layer that I want. In my code if the pathItem is on a layer named "651(Highways)" I want the swatch in my document labeled "651 (Blue Gray)" to be applied to all those pathItems.

Anyone help me out with that? I am sure it is simple but I have never done it before and not much luck Google'n it.

Here is my code....

#target illustrator
var doc = app.activeDocument;
var allLayers = doc.layers;
var allLines = doc.pathItems;
var allSwatches = doc.swatches;


// CHECK TO SEE WHAT LAYER PATH ITEMS ARE ON
for (var i = allLines.length-1; i >= 0; i--){
  if (allLines.layer == "[Layer Rails/Feather Bars]"){
  allLines.filled = false;
  lineFormat();
  blackStroke();
  allLines.strokeWidth = 2.0;
  }
  else if (allLines.layer == "[Layer 651 (Highways)]"){
  lineFormat();
  allLines.strokeWidth = 1.1;
  }
else {
  //alert("Found line on " + allLines.layer);
  }
}
function lineFormat(){
  allLines.filled = false;
  allLines.strokeWidth = 1.6;
  allLines.strokeJoin = StrokeJoin.MITERENDJOIN;
  allLines.strokeCap = StrokeCap.BUTTENDCAP;
  }
function blackStroke(){
  var blackLine = new GrayColor();
  blackLine.gray = 100;
  allLines.stroked = true;
  allLines.strokeColor = blackLine;
  }

try

allLines.fillColor = allSwatches['651 (Blue Gray)'].color;

That worked! Only thing I changed was .fillColor to .strokeColor

allLines.strokeColor = allSwatches['651 (Blue Gray)'].color; 

THANK YOU CARLOS!
