Conditional Header in wordpress

Question

I'm trying to modify the header in a theme for two specific custom post type. The header for all theme page is output from this code:

<script>
        jQuery(function($){

        $('.parallax-window').parallax({imageSrc: '<?php echo  $ilgelo_options['ilgelo-parallax-image']['url'];?>'});
        });
</script>

I've tried to put my condional code:

<?php if ( is_singular( array( 'rivista', 'rivista-trimestrale' ) ) ) {
    <script>
        jQuery(function($){

        $('.parallax-window').parallax({imageSrc: '<?php echo  $ilgelo_options['ilgelo-parallax-image']['url'];?>'});
        });
    </script>
} else {

<script>
        jQuery(function($){

        $('.parallax-window').parallax({imageSrc: 'STYLESHEETPATH."/img/header-rivista.jpg"'});
        });
    </script>
    } 
?>

but I get a syntax error '<' and I can't understand why. Could someone help me please? Thanks.

It seems that you have forgotten to use <?php and ?> properly. Remember to open and close the php tag like the following:

<?php if ( is_singular( array( 'rivista', 'rivista-trimestrale' ) ) ) {?>
    <script>
        jQuery(function($){

        $('.parallax-window').parallax({imageSrc: '<?php echo  $ilgelo_options['ilgelo-parallax-image']['url'];?>'});
        });
    </script><?php
} else { ?>

<script>
        jQuery(function($){

        $('.parallax-window').parallax({imageSrc: 'STYLESHEETPATH."/img/header-rivista.jpg"'});
        });
    </script><?php
    } 
?>
