[JS- CS3] Before Export Set pdfExportPresets

Question

I am having trouble setting the pdfExportPreset with a script I am using to do things before the Export Dialog box shows up.
I can set the pdfExportPreferences.pageRange with no problem. But can't get the pdfExportPresets to work.
Var myPreSet = app.pdfExportPresets.item("PDF Preset1");
with(app.pdfExportPresets){
name = myPreSet.name;

Hi David,
To make sure that your script always uses a certain PDF preset you can do it like so:
//Your PDF Export Preset is the name of your PDF preset as you see it in the user interface.
if (app.pdfExportPresets.item("Your PDF Export Preset") != null){
   myDocument.exportFile(ExportFormat.pdfType, myFile, false, "Your PDF Export Preset");
else {
   alert("Your PDF Export Preset is not installed");
   exit();
If you want to set the name of a preset as default in a dialog, you can do it like in this example:
myDoc = app.activeDocument;
fileNameWOExt = myDoc.name.split(".indd").join("");
var myPDFExportPreset = app.pdfExportPresets.item("Your PDF Export Preset");
var myPresetIndex = myPDFExportPreset.index;
pdfPresetDialog = app.dialogs.add();
with (pdfPresetDialog.dialogColumns.add()) {
  with (dialogRows.add()) {
    with (dialogColumns.add()) {
      staticTexts.add({staticLabel: "Choose PDF-export preset:"});
      with (dialogRows.add()) {
        pdfDD = dropdowns.add();
        sl = new Array();
        for (i=0; i < app.pdfExportPresets.length; i++)
          sl.push(app.pdfExportPresets[i].name);
          pdfDD.stringList = sl;
          pdfDD.selectedIndex = myPresetIndex;
    dialogColumns.add().staticTexts.add({staticLabel: " ", minWidth: 15});
    with (dialogColumns.add()) {
      dialogRows.add().staticTexts.add({staticLabel: "Name your file:"});
      pdfFileName = dialogRows.add().textEditboxes.add({editContents:fileNameWOExt + ".pdf", minWidth: 100});
    dialogColumns.add().staticTexts.add({staticLabel: " ", minWidth: 15});
pdfPresetDialog.show();
