Excel Invoice Sheet V2

General information for the business: Invoice - Excel
Description of requirements/functionality: I need the following to occur if possible with the new design.

1) The original Excel sheet worksheet "Invoice Template" should not be saveable i.e if the user closes it. None of the details entered can be saved within the actual work book. Thus forcing the user to press the Save PDF or Save Excel sheet button to save the details. Once the closed or X button is pressed It should just only re-set back to its original state i.e no details saved only having the excel sheets Invoice & addr.

2)None of the non mandatory fields should be changeable in both Invoice and addr . I am presuming I just need to protect the sheet to do this?

3) The location of where the file is saved should can be changed by the user in cell W16.

4) A delete button is pressed to clear the mandatory fields.

5) I need this all in excel 2003.

Thanks

Neil.
