Routing a spreadsheet for approval

I have a form that I plan to create in excel sheet that needs to be approved by multiple people.

This needs to be sent to the first person then they check approve (through a dropdown) and then hit the "route" button and it sends to the next person on the list and copies the previous and the HR person. I'm not a VB programmer by any means. Is there someone on this forum that has already done this and will be willing to share their file and/or knowledge?
