title: Add "Are you sure?" to my excel button, how can I?
body: <p>I have a button on my form that clears the entire 8 sheet workbook. I do want to clear it occasionally, but I would hate to do it by accident. I've tried googling it, but every result I've found assumes I have a much firmer grasp of VBA than I do. How can I make it so when the button is clicked a Dialog box pops up saying "This will erase everything! Are you sure? [Continue] [Cancel]"?
  Thanks.</p>
