I have a form with a Combo box. It uses an onUpdate method. When you select Invoice It opens a Form for invoice tracking.
Invoice Tracking has a main form with FacID and WorkOrder#, and a subform with various Invoice data.

I know how to open the form with an If Me.NewRecord function, but what I need is a method for opening the form with the WorkOrder# if it has been entered previously.

If workorder# exists then
open with that record.
Else open for entry.

Please Help. I offer Pre-Thanks.

PLEASE! Don't post the same question in multiple places. It just causes confusion.
