importTextData()

I have a simple text doc with 1 column of data, multiple rows
I wish to import this into a drop down
At the moment, I am just trying to read the text file and populate 1 text field with any one row of data

The text field's name is Main.Pg1.zProjectID
Do I need to have this full name in the Txt data file? or just zProjectID????

The Trusted function executes, but does not update the field?

The import button script is as follows:
var myFPathName = "/c/temp/myData.txt";
var myRow = "0";
console.println("myFPath. " + myFPathName );
myImportProjects2(event.target, myFPathName, myRow); // call the priv function

The Trusted Function is as follows:
var myImportProjects = app.trustedFunction(function(oDoc,cPath,cRow)
{
app.beginPriv();
try
{
console.println("Data Import.");
oDoc.importTextData(cPath, cRow);
app.alert("Text Imported:\n" + cPath);
}
catch(e)
{
app.alert("Error During import of Project Text Data.\n" + e);
console.println("Error Text Data Import.\n" + e);
}
app.endPriv();
});

And my text file looks like this
"Main.Pg1.zProjectID"
"12"
"103"

Can anyone shed some suggestions as to what I am doing wrong?
