External References Fail to Update in Excel 2010

[dmking99]

Thanks in advance for any help.

I just loaded Office 2010 and am working with Excel. In one of my Sheets i reference data from another sheet in the same Workbook.

When I make changes in the REFERENCED sheet, the external reference does not update.

I looked at the "Excel Help" which did not help.

Any clues?

Also, If I change the referenced cells, why doesn't the associated chart update?
