need a little help with a php value

hi,
how can i add in this code a third value

if ( $gender == '' ) {
        $errors[]               = $lang['signup.gender_err'];
    } else {
        $gender                 = ( $gender == 'Male' ) ? 'Male' : 'Female';
        $signup['gender']       = $gender;

Code (markup):

this gives only an error message

if ( $gender == '' ) {
        $errors[]               = $lang['signup.gender_err'];
    } else {
        $gender                 = ( $gender == 'Male' ) ? 'Male' : 'Female' : '????';
        $signup['gender']       = $gender;

Code (markup):

 

Following would help..

if ( $gender == '' ) {
        $errors[]               = $lang['signup.gender_err'];
    } else {
        $gender                 = ( $gender == 'Male' ) ? 'Male' : ($gender == 'Female'  ? 'Female' : '????');
        $signup['gender']       = $gender;
