I have a file I would like to include on the editprofile page. Rather than edit all of the templates and include it in every one I thought it would be easier to make a hook that appends it to all of them. However when I tried this for some reason the $headinclude variable gets replaces with only "0".

PHP Code:

if ($_REQUEST['do'] == 'editprofile'){
    $headinclude += '<script type="text/javascript" src="/includes/bubbles.js"></script>';
} 


PHP Code:

echo htmlspecialchars($headinclude);
echo '<br><br><br>';
$headinclude += '<script type="text/javascript" src="/includes/bubbles.js"></script>';
echo htmlspecialchars($headinclude); 


Output of above code:
