2 Forms in Nav Bar

Hi there, my URL is http://74.54.88.165/~rwatchi/. I have placed two images in the top navigation bar and each one should link to a form. The first is Email This Page, which should email the url of the page the form is filled out on. The form is set up with an Email field and a hidden field using {embed_url}. Then {embed_url} is inserted into the Body of the notification email sent to the Email address the user fills out in the form field. On the form, the Field Label is url, I have checked to allow to populate dynamically, and the Parameter Name is refurl. Looking thru the forum, I found a snippet that I put in functions.php 'add_filter("gform_field_value_refurl", "referral_url");
function referral_url($form){
//Grab URL from HTTP Server Var and put it into a variable
$refurl = $_SERVER['HTTP_REFERER'];

//Return that value to the form
return esc_url_raw($refurl);
}'

The second form is linked to the image "Product Tour", and is simply designed to capture the Name, Company Name and Email address of the person who is taking the tour (clicks on the button and fills out the form). Nothing special with this form, very simple.
In looking thru the forum and documentation, it looks like I need to use tabindex for more than one form on a page, so I have added 'add_filter("gform_tabindex", create_function("", "return 1;"));' to the functions.php file, and also added '<?php
gravity_form_enqueue_scripts(3,4, true);
?>' in the header.php file. (Not sure of the syntax for allowing forms 3 & 4 ??)
I wish to display both forms in a Fancybox, so I have installed Easy FancyBox and added this code to my functions.php: 'add_filter ('wp_nav_menu_menu_items','add_producttour', 10, 2);
function add_producttour($items, $args) {
$items .= '<li class="my-contactus"><div style="display:none" class="fancybox-hidden"><div id="fancyboxID-1"> <?php gravity_form(3, true, true, "", "", true, 4); ?> </div></div><img src="http://74.54.88.165/~rwatchi/wp-content/themes/BuilderChild-Default/images/ptnav.png" alt="Product Tour" />';
return $items;
}
add_filter ('wp_nav_menu_menu_items','add_contactus', 10, 2);
function add_contactus($items, $args) {
$items .= '<li class="my-contactus"><div style="display:none" class="fancybox-hidden"><div id="fancyboxID-1"> <?php gravity_form(4, true, true, "", "", true, 1); ?> </div></div><img src="http://74.54.88.165/~rwatchi/wp-content/themes/BuilderChild-Default/images/emailnav.png" border="0">';
return $items;
}'
I had to change the single quotes in the GF parameters because it was giving an error. I've tried single quotes, double quotes and just a space without any luck. I do not know php very well.
I have used the FancyBox plugin on another site w/GForms with no problems, but as you can see when you go to the URL, it's not working and I've tried searching the forums and documentation....can you please help? Thanks so much.

Thanks for the quick reply. So I have removed one of the forms to try to get a single form to work before going to the second. Here's what I have in functions.php,
'add_filter("gform_tabindex", create_function("", "return 1;"));

add_filter ('wp_nav_menu_menu_items','add_producttour', 10, 2);
function add_producttour($items, $args) {
$items .= '<li class="my-contactus"><div style="display:none" class="fancybox-hidden"><div id="fancyboxID"> <?php gravity_form(3, true, true, true, 4); ?> </div></div><img src="http://74.54.88.165/~rwatchi/wp-content/themes/BuilderChild-Default/images/ptnav.png" alt="Product Tour" />';
return $items;
}

add_filter("gform_field_value_refurl", "referral_url");
function referral_url($form){
//Grab URL from HTTP Server Var and put it into a variable
$refurl = $_SERVER['HTTP_REFERER'];

//Return that value to the form
return esc_url_raw($refurl);
}'
This is for the Email to a Friend form. Searching the Fancybox forum I found this post on classes/ID's:
https://groups.google.com/group/fancybox/browse_thread/thread/736736f5d556c67b#
The URL to the site is: http://74.54.88.165/~rwatchi/ and it still doesn't display the form. I've tried modifying this code in the functions.php ('<?php gravity_form(3, true, true, true, 4); ?>') because when I use single quotes for the $field_values attribute it would give an error. I even tried to use echo do_shortcode to avoid the single quotes. I'm really struggling here and looking for World Class Support that you guys are know for...I think it's close and if you would like access to login if you think that would help I can provide it via email. Thanks for all you do.

In the term wp_nav_menu_menu_items, the first occurrence of "menu" is the name of the Custom WP Menu, it just so happens I named it menu. If I called the menu Top Nav then it would be wp_nav_top-nav_menu_items. Hope that helps.

I think the confusion lies in the fact that I'm using Builder by iThemes, and I think the term comes from within Builder...

Yep, works just fine. You have to look close because the text is BLACK and it is on the Navy blue background between NEWS/EVENTS and the orange Email Page button.

The box appears but the form does not display...still need some help. Thanks for all you do.
