[JS][CC2015] What's a good way to write a "save as intereactive pdf" script?

Hello!

i'm a beginner at scripting and i'm having a hard time finding clear explanations (jongware is great for the initiated but not me...).

Anyways, i'm trying to make a script that will do the following :

- save the active document as an interactive document

- with some options (magnification, jpeg quality, layout etc.)

On some docs it works well on some others i get the "Data is out of range" error, and i have no idea what to do with this or why it happens =/

I've had hard time is setting the options. the syntax seems complicated to me. maybe thats what's causing the trouble.

But here is the script i have so far. Feel free to correct =/

app.scriptPreferences.version = 11.0
var myDocument = app.activeDocument;
var myFileName;
if (myDocument.modified == false) {
    myFileName = myDocument.fullName + "";
    if (myFileName.indexOf(".indd") != -1) {
        var myRegularExpression = /.indd/gi;
        myFileNamePDF_Web = myFileName.replace(myRegularExpression, ".pdf");
    }
    with(app.pdfExportPreferences) {
        PDFJPEGQualityOptions.HIGH;
        PdfMagnificationOptions.FIT_PAGE;
        PageLayoutOptions.SINGLE_PAGE;
        colorBitmapCompression = BitmapCompression.zip;
        colorBitmapQuality = CompressionQuality.eightBit;
        colorBitmapSampling = Sampling.BICUBIC_DOWNSAMPLE;
        colorBitmapSamplingDPI = 300;
    }
    myDocument.exportFile(ExportFormat.INTERACTIVE_PDF, new File(myFileNamePDF_Web));
} else {
    alert("Save your file before continuing");
}
