Then you must use a session variable to hold the values between each submission.  Each time you submit the form and issue a POST (or GET), the PHP runs again.  Any variables that are used only exist during that one running of the script.  They go away again as soon as it's done.  So, replace $chosenatotal with $_SESSION['chosenatotal'] (and the "b" version) and see what happens.  You'll need session_start() at the top of your script, as well.
