Assume that you paste a range of cells as formulas into a merged cell in Microsoft Excel 2000, in Excel 2002, in Excel 2003, in Excel 2007, or in Excel 2010. In this scenario, the paste may apply the formula to each underlying cell of the merged cell, if the source range is not also a merged cell of the same size. Excel then calculates the result by using all the formulas in the underlying cells of the merged cell. This is expected. However, because you only see one of the component cells of the merged cell, the calculation result might differ from the result that you expect. Additionally, the results of certain aggregation functions, such as the Sum aggregation, as displayed in the status bar do not match the expected results based on the visible data.
