Getting problem as "Unspecified" Error at while loop

Problem : Getting problem as Unspecified Error at while loop (at different while loop) in our script.

Description : refExcel is our excel file object.

Following is an example:

var refExcel = DDT["ExcelDriver"]("Sheetname");

while (!refExcel ["EOF"]()) { }

1. Problem dosen't occure all the time and at the same while loop.

2. We are using the following code for closing the driver :

refExcel["Close"];

DDT["CloseDriver"](refExcel["Name"]);





Kindly provide with your best solution for this problem.



Thank you,
