XL2000: Moving Average Period Reduced by 256 After You Save the File

In Microsoft Excel 2000, when you open a file that contains a chart, some or all of the trendlines on the chart may not be displayed correctly.

This behavior can occur if the following conditions are true:

�	Your chart contains a moving average trendline. -and-
�	You set the Period value of the trendline to a value greater than 255.

If a moving average trendline's Period value is 256 or greater, this value is reduced by 256 when you save and reopen the file that contains the chart.

For example, a moving average trendline with an initial Period value of 365 has this value reduced to 109 (365-256=109) when you save and reopen the file. An initial Period value of 256 is reduced to 0 (zero) when you save and reopen the file.

Microsoft has confirmed that this is a problem in the Microsoft products that are listed at the beginning of this article.
