An image attachment almost never has value. Don't attach a screenshot of your Excel file--just attach the file! It's easier than taking a screenshot first and then attaching that.

When you create a radio button, you drag it out to whatever size you want it to be. If you create it so that it fills the cell, then you can click anywhere in the cell to activate the button. In your example, there are no labels, but trust me--the radio button fills the cell.
