Correcting Formulas
Excel has several tools to help you find and correct problems with formulas. One tool is the Watch window and another is the Error checker. The Watch window keeps track of cells and their formulas as you make changes to a worksheet. Excel uses an error checker in the same way Microsoft Word uses a grammar checker. The Error checker uses certain rules, such as using the wrong argument type, a number stored as text or an empty cell reference, to check for problems in formulas.
