When Excel finds a possible error in a calculation, it displays a green triangle in the upper left corner of the cell . If Excel can't complete a calculation it displays an error message, such as "#DIV/0!". You can use the Error smart tag to help you fix the problem. In a complex worksheet, it can be difficult to understand the relationships between cells and formulas. Auditing tools enable you to clearly determine these relationships. When the Auditing feature is turned on, it uses a series of arrows to show you which cells are part of which formulas. When you use the auditing tools, tracer arrows point out cells that provide data to formulas and the cells that contain formulas that refer to the cells. A box is drawn around the range of cells that provide data to formulas.
