[Plugin: WordPress Form Manager] add into custom page implement with colorbox

Hi guys,

I am looking for solutions on how to insert my form into a custom page template and implement into colobox pop up.
Assume that I had already have jquery library and colobox js as well.
I have added my form into a page which is page id = 963.

My codes:
1. In my header.php I have <a href="#enquiryform" class="colorbox-inline">Enquiry</a>
2. In jquery init: $(".colorbox-inline").colorbox({ inline: true });
3. In the footer.php, I insert these codes:

<div class="hidden">
	<div id="enquiryform" style="display: block; width: 800px; height: 600px; background-color: #fff; color: #555;">
		<?php $recent = new WP_Query("page_id=963"); while($recent->have_posts()) : $recent->the_post(); ?>
		<?php the_content(); ?>
		<?php endwhile; ?>
	</div>
</div>

My problem is when I click on Enquiry link, the colorbox popup but didn’t show the form. When I click on the second time, the colorbox popup with no width and height (is an empty content).

I think is my wp_query something goes wrong. I still learning wordpress codes and still in beginer level. Hope can get solutions here.
