Save UserForm and reopen later semi-complete and resume

Hi,

I have quite a long form that the users have stated they want to pause halfway and resume.

I currently have the following code to save and close:

    End With
    ActiveWorkbook.SaveAs ([txtStudentLast])
    ActiveWorkbook.Close
    End Sub

but when I reopen it the data is written to the background sheet but the UserForm is empty ready for another entry. Can anyone help with code that would open the form where it left off? Ideally I'd want one button to "Save and Resume Later" and one button to "Save and Finish" - I suppose what I currently have is Save and Finish.

Thank you
