how do I call custom field after header in childtheme..

[PeteG]

Hi,

I'm tying to call a custom field as a string underneath the header.
Custom filed is called "welcomemsg".
I've identified the hook as genesis_after_header.

Below is how I called the custom field through child theme's functions.php

add_action('genesis_after_header', 'page_welcom_message');
function page_welcom_message() { ?>
get_post_meta($post=>ID, 'welcommessage', true);
 <?php }

Instead of the message I typed in to custom field in this code spits out the blow just after header. What is that I'm doing wrong here?
get_post_meta($post=>ID, 'welcommessage', true);

Thank you.
Pete.
