A better way to do this may be to use the form's Error event. When an error occurs in your form, if there is code in the Error event, it will take precedence over any On Error. You can have code in it to call your global error handler with the error information plus an object reference to the form that caused te error. Using the reference you can gather any information you want about the form.
