Deposit Script to Allow Deposit Import

Hi-we tried the suiteanswers script (below) to see if we can do the workaround to allow for bank deposit imports, and it won't work.  NetSuite states we'll need custom work by them to get it working.  Anyone figure out how to get this to work?

// load csv file from file cabinet
    var arrLines = nlapiLoadFile(1913).getValue().split(/\n|\n\r/);

    // loop to get all lines
    for (var i = 1; i < arrLines.length - 1; i++) {
        var content = arrLines[i].split(',');

        // add the columns of the CSV file here
        var customer = content[0]; //first column
        var payment = content[1]; //second column

        // create customer deposit using fields from csv
