The information in this article applies to:

Active Server Pages
Microsoft Internet Explorer version 5 for Windows NT 4.0

SYMPTOMS

When using the VBScript function FormatNumber in Active Server Pages (ASP), the following error might occur:

ASP 0115 Unexpected Error. A trappable error occurred. The script cannot continue running.

CDB: integer divide by zero

Make sure that VBScript is on the call stack (Vbscript.dll, version 5.0x).

CAUSE
