XL: Iteration May Not Be Calculated Correctly

• Microsoft Excel for Windows 95, version 7.0

SYMPTOMS

When you use circular reference formulas in a worksheet, the resulting values may be incorrect; it may appear that Microsoft Excel did not perform the specified number of iterations.

CAUSE

This problem may occur if the following conditions are true:

• You select the Iteration check box on the Calculation tab (click Options on the Tools menu).


-and-


• You type a formula that gets a starting value from another cell and creates a circular reference.
  
  For example, this problem occurs when you type the following:

  A1: 10
  A2: =A3/10
  A3: =A1+A2



-and-


• You decrease the value in the starting cell (cell A1 in the example).

STATUS

Microsoft has confirmed this to be a problem in the Microsoft products listed at the beginning of this article. This problem has been corrected in Microsoft Excel 97 for Windows.
