Novice: Requires knowledge of the user interface on single-user computers.

This article applies to a Microsoft Access database (.mdb) and to a Microsoft Access project (.adp).



SYMPTOMS
When you export a Microsoft Access object (a form or a report) by using the XML Documents setting, and you include an HTML 4.0 presentation file, you may receive an error message similar to the following when you attempt to view the HTML document in your Web browser:

A Runtime Error has occurred.

Do you wish to Debug?

Line: 19

Error:

Microsoft VBScript runtime error

Type mismatch: 'CVar'

line = 1, col = 0 (line is offset from the  tag).

Error returned from property or method call.



CAUSE
This behavior can occur if you export an Access object that uses a Microsoft Visual Basic for Applications (VBA) function that is not supported by Visual Basic Scripting Edition (VBScript).



RESOLUTION
To work around this issue, either remove the function that is causing the problem or replace it with a similar function that is supported by VBScript. For a list of functions that are supported by VBScript, refer to the VBScript Language Reference available on the Visual Basic Scripting home page at the following Microsoft Web site:

http://msdn2.microsoft.com/en-us/library/ms950396.aspx

To determine which VBA function is causing the problem, examine the run-time error that you receive for clues. For example, in the error message described in the &quot;Symptoms&quot; section, the line that reads &quot;Type mismatch: 'CVar'&quot; indicates a problem with the CVar function, which is not supported by VBScript.



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