I am new to VBScript Programming; thus, I am unfamiliar with VBScript Error Objects.
However, I think that you probably should use a MsgBox for your Error Message.
EXAMPLE:
Code:
MsgBox Err.Raise vbObjectError + 15000, _
"ERR_MSG_UGLY.VBS", _
"Hey, stupid, you can't enter a zero. It will " & _
"cause a divide by zero error."
