Hey,
I’m working on a child theme for a theme which uses a it’s own functions.php which overrides it’s parent theme. When I upload the functions.php file i get the white screen.
Can anyone look at the code and help me fix it.

<?php

function childtheme_menu() {
    echo '<div id="nav">

<ul id="menu">
    
    <li id="aboutmenu"><a href="get_option('home') /about" title="About">About<em ></em></a></li>
    
    <li id="teammenu"><a href="get_option('home') /team" title="Team">Team<em></em></a></li>
    
    <li id="goalsmen"><a href="get_option('home') /plans" title="Plans">Plans<em></em></a></li>
    
    <li id="newsmenu"><a href="get_option('home') /blog/" title="News">News<em></em></a></li>
    
    <li id="donatmenu"><a href="get_option('home') /donations" title="Donate">Donate<em></em></a></li>
    
    <li id="contmenu"><a href="get_option('home') /contact-us" title="Contact">Contact<em></em></a></li>
</ul>

</div>';
}

add_filter( 'sandbox_menu', 'childtheme_menu' );

function secondary_header() {

if ( is_front_page() ) {?>
    <?php echo '<div id="homecont">
    
<div id="homeframe">
<span>1</span>

<div id="headleft">
<div id="homeinfo">
<li id="whatis">Donate</li>
