Using the Consolidation feature. You can determine whether or not the link will be interactive when creating the consolidation. This method provides the greatest level of detail in the summary worksheet. You can choose between any function, not just the sum function. For example, you could create an average of several divisions in a summary worksheet. Some of the disadvantages of this method are that the worksheets must be identical. Although it is not impossible, it is difficult to use consolidation across workbooks.
Creating a Sum across worksheets. This is also an inter_active link. If a number changes on one worksheet, the sheet with the summary formula will also be updated. If a worksheet is inserted between worksheets in the sum, the sum will automatically be updated. Some of the disadvantages of this method are that all of the linked cells must be in the same location on all worksheets. Also, you can only sum one cell at a time (although you can copy the formula to other cells in the summary worksheet.) Using group mode to create identical spreadsheets will help when using the sum function across worksheets. This method is also limited to within a workbook and cannot be done across workbooks.
