The information in this article applies to:
In Microsoft Excel, when you use the Function Wizard, a custom function may appear in a category that is different from the category assigned to that custom function. This problem will occur only if you have assigned a function to a category that you created.
The built-in categories appear at the beginning of the category list in the Function Wizard. The order for these built-in categories does not change; instead, the custom categories are added to the end of the category list.
When you assign a function to a specific category, Microsoft Excel actually assigns the function a number that represents that category (the categories are numbered as they appear in the Function Wizard). When you open a new workbook in Microsoft Excel, any custom categories contained in that book are simply appended to the current list of categories. Thus, the order in which workbooks are opened can effect the order that custom categories appear in the Function Wizard.
To work around this problem, assign the function to one of the built-in categories since the order for these categories will not change.
Microsoft has confirmed this to be a problem in the products listed at the beginning of this article. We are researching this problem and will post new information here in the Microsoft Knowledge Base as it becomes available.
