InDesign Server Automation

I'm looking into purchasing InDesign Server for the document automation features. One feature, Data Merge, would be a tremendous help for our company.

I'm having some trouble setting it up with a script.

Here's what I have running, just a basic test.

var myDocument = app.open(File("C:\\inetpub\\wwwroot\\indesign\\test.indd"));


with (app.dataMergeOptions) {
linkImages = true;
removeBlankLines = false;
createNewDocument = true;
documentSize = 100;
} // (end of dataMergeOptions)


myDocument.dataMergeProperties.mergeRecords();
myDocument.exportFile(ExportFormat.PDF_TYPE, File ("c:\\inetpub\\wwwroot\\indesign\\merged.pdf"));
myDocument.close ();

In the file I had it linked to a csv that pulled data but it seems the link has been broken (or out of date according to the error).

Can anyone help me with what I am doing wrong or even provide a better method?

I am running the script through PHP via SOAP in IIS running on Windows 2008 R2
