Need help with JS data merge script

[DavidRock]

InDesign CS with PageMaker plugin on Windows.

Using the JS data merge example from the scripting addendum, I'm able to merge all records into my document. But I don't understand how to only merge a single record. I included the script I'm using below. The addendum indicates I need to use RecordSelection.oneRecord and recordNumber to do what I need, but everything I've tried only generates errors, mostly "undefined is not an object". Can someone show me how to set those properties in this JS script so that I can merge any record I want?

current script:

if(app.documents.length != 0){
var myDocument = app.activeDocument;
app.dataMergeOptions.removeBlankLines = true;
// app.dataMergePreference.RecordSelection.oneRecord ???
//Select a source file.
var myDataFile = File.openDialog("Select a data file")
if(myDataFile != ""){
myDocument.dataMergeProperties.selectDataSource(myDataFile, DataSourceType.commaSeparated);
myDocument.dataMergeProperties.mergeRecords();
}
}

Thank you in advance to anyone who can help me out.

If haven't done so already, I'd recommend taking this to the ID scripting forum on the Adobe web site.

I have a thread started on Adobe's scripting forum also. Unfortunately, I'm beginning to conclude that there isn't anyone who frequents the forums who has scripted a data merge using InDesign and JS. Adobe support indicated they can't answer scripting questions, even ones to clarify syntax found in their guide.
