That is a very resonable request, but this system is huge and code seems to be hidden everywhere. Combine that with my lack of knowledge and I just don't know. Would the code to open the file have to be in the form or is it possible to open the files before the form is opened?

What commands open a table? Does SEEK open the file or do you have to open it then SEEK?

The form is the invoice header. There is a listbox that has the detail items displayed. To actually change the detail items you click on a details button.

Sorry for the lack of knowledge here.
