RussianAlright, so I figured it out with some of Spudley's advice. I was running into a situation where the html was rendering && in the javascript as && This is due to a quirk of wordpress and its use of XHTML as described here. I tried using their suggestions but none of them did it for me. Finally I just created a separate javascript file and referenced it in the php heredoc.
Javascript working fine in HTML but not in PHP Heredoc

Question
I'm a major noob to php and I might be biting off more than I can chew here. That being said, I'm facing the following problem: I've created a form using HTML that dynamically generates additional rows for responses using javascript with the click of a button. It works fine as a stand-alone html document, however, when I try to use heredoc to put it into a php function, the buttons don't add any rows. See my code below.
Thanks in advance for any insight!
function upsmart_create_profile_form() {
global $wpdb;
$data = $wpdb->get_row($wpdb->prepare("SELECT * FROM upsmart_profile WHERE wordpress_id=%d",get_current_user_id()),ARRAY_A);
$media_url = admin_url("media-upload.php?type=image&TB_iframe=true");
$out = <<<EOHTML
<form method='post' enctype='multipart/form-data'>

When using HEREDOC, make sure your HEREDOC line ending has NO spaces in front of it.
Example:
<?php
$myStr = <<< ENDL
Hello, World!
ENDL; // No white space in front of me!
?>
