ID: Q131237
The information in this article applies to:
In the versions of Microsoft Excel listed at the beginning of this article, when you attempt to display a dialog box over another dialog box, and the first dialog box contains a text box that has the Reference or Formula "Edit Validation" type, you may receive the following error message:
Run-time Error '1004':
Show method of Dialogsheet class failed
This error occurs when the second dialog box is displayed during an event
macro of a control on the first dialog box, and the first dialog box has
not been unloaded.
This is a known limitation with Microsoft Excel 5.0 style dialog boxes. You cannot stack a semi-modeless dialog box (any dialog box that has a Reference or Formula type edit box) on top of another dialog box.
To work around this limitation, use any of the following methods.
1. Select the edit box.
2. On the Format menu, click Object.
3. Click the Control tab, and then click a Type other than Reference or
Formula.
Unload the first dialog box before you show the second dialog box (which contains the Reference or Formula type edit box).
If you are using Microsoft Excel 97, use UserForms instead of Microsoft Excel 5.0 dialogs. UserForms do not have this limitation.
For additional information, please see the following article in the Microsoft Knowledge Base:
