Save Copy As Same Path And Name

I want a Macro which will copy my workbook and paste it into a new workbook. Then it will automatically save it under the SAME name as the original and the SaveAs Box must show up (for cosmetic fixes). It is important it asks if it wants to save it under the same name. Example: My file is called "Summary_2008" and when I hit the Macro it will do those things and it will ask me if I want to save it in the SAME directory under the name "Summary_2008" (I will only add a number then).

(The macro must know how to read the original name since I have 7 possible filenames - it depends on which company I choose, that is why it is important it is saved under the same name)
