XL2000: "Compile error: Invalid Qualifier" Using "Checked", "Gray", and "Unchecked" in Macros

When you run a Visual Basic for Applications macro, you may receive the following error message:

This problem occurs if the following conditions are true:

• You have controls in a custom dialog box named "Checked", "Gray", or "Unchecked" (without quotation marks).
  
  -and-
  
  
• In your macro, you enclose the name of one of the controls in brackets when referring to it, for example:

  [Checked].Value = xlOn
  						

NOTE: This problem does not apply to controls named "Grey".

To work around this problem, use either of the following methods:

• Rename your controls so that none of them are named "Checked", "Gray", or "Unchecked". If you do this, you will also need to modify your Visual Basic macro code so that it refers to controls by their new names.
  
  -or-
  
  
• Within your macros, replace all occurrences of "[controlname]" with a proper reference to the specified control. For example, if your macro contains the following line of code

  [Unchecked].Value = xlOff
  						

  and "Unchecked" is the name of a check box within your custom dialog box, change the line to read:

  ActiveDialog.Checkboxes("Unchecked").Value = xlOff
  						

  If you do this throughout your macro code, you can still use controls named "Checked", "Gray", and "Unchecked".

In versions of Microsoft Excel earlier than Excel 97, the words "Checked", "Gray", and "Unchecked" have no special meaning. However, in Microsoft Excel 2000, these three words are global constants belonging to the Stdole Type Library.

Because of this, it is not possible to refer to these constants by enclosing them in brackets when running a macro in Microsoft Excel 2000.
