mail signature issue - probably an easy fix

so i know this is probably a stupid question.

but in mail, i cant figure out how to get my signature to appear at the top of the message.

example: when i reply to an email it automatically puts it at the bottom of the message, below the copy of the email i'm replying to.

let me know if anyone knows how to fix this or if you need any more information.

thanks

 

and i feel retarded

thanks though, i mustve looked at that page 100 times without seeing that one checkbox
