Specifying the cells of the custom worksheet which will allow modification
This area allows the selection of the cells that can be edited by the end-users. For example, one might decide to allow users modify the NGP (New Gross Profit) and NMU (New Mark Up) percentages to see how the Pay Rate and Bill Rates (respectively) would be affected. Simply add the cell(s) to the listing using a comma separator, and these fields will then be user-editable.
Use the Clear button to remove the contents of the Custom worksheet: editable cells (comma separated) field.
