The reason is because you are using 8 variables/strings seperated by commas, php thinks those are parameters for the mail function...
You need to combine the variables into
1 variable and put the string into the mail function.
PHP Code:
$string = "$pre, $first, $last, $phone, $message";
mail( "jbuche@westerniplaw.com", "Feedback Form Results",
$string, "From: $email" );
Or change the string if i didnt pick up on that one correctly.
