Each module or spreadsheet is set up so that data may be entered only in appropriate cells. All other cells are locked. We have not offered the Planning Templates files in an unlocked fashion. We have taken this position in an effort to protect our work as well as to maintain a level of control over the results achieved by a product with the Planning Templates, Inc. name on it. To move between the data entry cells simply click on the desired cell or use the tab key to cause the curser to advance to another data entry cell. Most data entry cell characters appear in dark red unless otherwise noted in the spreadsheet file. The characters for most calculated numbers will be blue or black.
