Creating an object style with a drop shadow

Hello,

I'm modifying an existing free script that adds measurements to a selected object. I'm trying to create an object style that has a drop shadow and I'm not sure how to write the proper syntax for creating this object style.

Here's the code where I'm creating the object style:
It works until I try to add in the part with the transparency settings, drop shadow mode, angle, offset and size. I know I have something in the syntax wrong.

    // Make sure the object style "Shadow" exists
  try {
  app.activeDocument.objectStyles.add({name:"Shadow", strokeColor:"None", fillColor:"None", strokeWeight:0, transparencySettings.dropShadowSettings{mode:ShadowMode.drop, angle: 0.0083, xOffset: 0.08, yOffset: 0.08, size: 0.6 }});
  } catch (_) { }
  reportObjectStyle = app.activeDocument.objectStyles.item("Shadow");

Here's the full code:

if (app.documents.length && app.selection.length == 1 && app.selection[0].hasOwnProperty("paths"))
{
  app.doScript(labelItem, ScriptLanguage.JAVASCRIPT, app.selection[0], UndoModes.ENTIRE_SCRIPT, "Label Image Size");
} else
{
  alert ("No valid selection.\nPlease select one single object with the black arrow before running this script.");
}

function labelItem (item)
{
  // Save current selected layer because adding one will make it active!
  activeLayer = app.activeDocument.layoutWindows[0].activeLayer;
  // Make sure the layer "ImageSize" exists
  try {
    app.activeDocument.layers.add({name:"ImageLabel", ignoreWrap:true, layerColor: [90,192,90], printable: false});
  } catch (_) { }
  reportLayer = app.activeDocument.layers.item("ImageLabel");

  // Make sure the swatch "ImageGreen" exists
  try {
    app.activeDocument.colors.add({name:"ImageLabel", space:ColorSpace.RGB, colorValue:[90,192,90], colorModel:ColorModel.PROCESS});
  } catch (_) { }
  reportGreen = app.activeDocument.swatches.item("ImageLabel");

  // Make sure the paragraph style "ImageSize" exists
  try {
  app.activeDocument.paragraphStyles.add({name:"ImageLabel", appliedFont:"Arial", fontStyle: "Bold", fillColor:"Paper", strokeColor:"Black", pointSize:22, leading:23, verticalJustification:VerticalJustification.topAlign});
  } catch (_) { }
  reportStyle = app.activeDocument.paragraphStyles.item("ImageLabel");
  
    // Make sure the object style "Shadow" exists
  try {
  app.activeDocument.objectStyles.add({name:"Shadow", strokeColor:"None", fillColor:"None", strokeWeight:0, transparencySettings.dropShadowSettings{mode:ShadowMode.drop, angle: 0.0083, xOffset: 0.08, yOffset: 0.08, size: 0.6 }});
  } catch (_) { }
  reportObjectStyle = app.activeDocument.objectStyles.item("Shadow");

  // Make sure measurement units are in inches  
  hmmu = app.activeDocument.viewPreferences.horizontalMeasurementUnits;
  vmmu = app.activeDocument.viewPreferences.verticalMeasurementUnits;
  app.activeDocument.viewPreferences.horizontalMeasurementUnits = MeasurementUnits.INCHES_DECIMAL;
  app.activeDocument.viewPreferences.verticalMeasurementUnits = MeasurementUnits.INCHES_DECIMAL;
  // .. and Smart Quotes is Off
  sqt = app.activeDocument.textPreferences.typographersQuotes;
  app.activeDocument.textPreferences.typographersQuotes = false;
  // Save all of the previous settings to be able to restore them later :)

  // fetch width and height for the numbers, left and bottom for the lines
  gb = item.geometricBounds;
  // gb now holds [ top, left, bottom, right ] values -- get shorthand values
  top = gb[0];
  left = gb[1];
  bottom = gb[2];
  right = gb[3];

  width = Math.round(Math.abs(right - left)*1000)/1000;
  height= Math.round(Math.abs(bottom - top)*1000)/1000;
 square_inches = Math.round(Math.abs(width * height)*100)/100;

  // Retrieve the current page.
  // Actually, in CS5 and newer, page items have a property for this (parentPage),
  // but I don't have that one near, and it's also nicer to make it work in CS4
  // (and possibly even in older versions).
  pg = item.parent;
  while (1)
  {
    if (pg instanceof InsertionPoint)
      pg = pg.parentTextframes[0];
    if (pg instanceof Document || pg instanceof Spread || pg instanceof Page)
      break;
    pg = pg.parent;
  }
  // Draw text frame for square inches
  // Put it at the left of the selection, 0.5" wide and 0.2" off the left side
  frh = pg.textFrames.add(reportLayer, {geometricBounds:[ top + 0.0819, left + 0.0819, top + height, right ],
    textFramePreferences: {strokeWeight:0, strokeColor:"None", verticalJustification: VerticalJustification.TOP_ALIGN, 
    ignoreWrap: true } } );
frh.applyObjectStyle(app.activeDocument.objectStyles.item("Shadow"));
//frh.applyObjectStyle("Shadow");
  // ... and put text into it.
  frh.insertionPoints[0].appliedParagraphStyle = reportStyle;
  frh.contents = String(square_inches)+'"';

  // Restore old layer selection
  app.activeDocument.layoutWindows[0].activeLayer = activeLayer;

  // Restore previous global settings
  app.activeDocument.viewPreferences.horizontalMeasurementUnits = hmmu;
  app.activeDocument.viewPreferences.verticalMeasurementUnits = vmmu;
  app.activeDocument.textPreferences.typographersQuotes = sqt;
