I may have over-reacted (better safe than sorry), but I deleted your attachment as it looked like it contained a real birthdate and real Social Security Number for the person you listed on the Data sheet. I have a copy of it and will look at it later (I have to go away from my computer in a few minutes), but if you want others to look at it while I am gone, please repost your workbook and use a birthday like 1/1/2012 and a Social Security Number like 123-45-6789 so we know that cannot be real. In any event, I had no trouble opening the workbook you posted... no errors at all.
