Script won't output bleed on PDF export, and stuck on other portion of script

So, the following script is a modified version of the script I found here. Its goal is to:

1. Export the current page as a PDF using the HQ Print default


2. Check for bleed. If there is one, the bleed will be included in export.


3. Extract the content of the second text frame (in top to bottom order) it finds on the page


4. Extract the first two words of that text, flip their order, add a dash between them, then prepend it to the file name.


5. Export the file

As of right now, the only thing I've managed to get working is item #1. For some reason this script won't export bleed no matter what I do, though InDesign's own documentation suggests that what I have in there should work. Also, I've been unable to puzzle out the correct way to handle items 3 and 4; I tried to modify the GetDate function to handle this, but it didn't work (as you can see from the commented out lines).

So scripting gurus of StackExchange, what am I doing wrong? Any and all help will be much appreciated. Thanks!

*Note-- I don't actually need the date appended to the filename; I was just using the GetDate function as a container for the name extraction code, since the function was already there in the code.

var scriptName = "Export current page to PDF - 1.0";  

Main();

var doc = app.activeDocument;

var page = app.activeWindow.activePage;

documentBleedOutsideOrRightOffset;
//If any bleed area is greater than zero, then export the bleed.
if(bleedBottom == 0 && bleedTop == 0 && bleedInside == 0 &&
    bleedOutside == 0){
    useDocumentBleedWithPDF = true;
    }
    else{
            useDocumentBleedWithPDF = false;
    }
}


var fileName = doc.name.replace(/\.indd$/, "") + "_" + GetDate() + ".pdf";  
var file = new File("~/Desktop/" + fileName);

var myExportPreset = app.pdfExportPresets.item("[High Quality Print]");
alert (myExportPreset);
doc.exportFile(ExportFormat.pdfType, file, false, myExportPreset);  
}

//var page = app.activeWindow.activePage; 
//var nameFrame = page.textFrames.item(1).contents;
//var employeeName = nameFrame.substr(2)

    var date = new Date();  
    if ((date.getYear() - 100) < 10) {  
  var year = "0" + new String((date.getYear() - 100));  
   }  
 else {  
   var year = new String((date.getYear() - 100));  
   }  
  var dateString = (date.getMonth() + 1) + "-" + date.getDate() + "-" + year + "_" + date.getHours() + "-" + date.getMinutes() + "-" + date.getSeconds();  
return dateString;  
}
