New form fails to submit, general contact form works fine

Hi All,
I have created a new form that is quite extensive and am using a few hooks to get taxonomy terms to list as checkboxes. My site is a directory and this form is to function as registration of new sites/companies to be listed. Since my general contact form works flawlessly there has to be another issue with my new form. Here is the link to the registration form: http://directory-sexy.com/lingerie-directory-registration/ and my gen contact form is here: http://directory-sexy.com/contact/

I can only think of two things causing the problem(but could be totally wrong here):
1. My code for adding in the taxonomy terms is causing an issue,
2. My server does not allow that much data to be posted - its a large form.

Here's a sample of my hook function:

add_filter("gform_pre_render_25", populate_lingerie_category_checkbox);
//categories
//form id 25 field id 31
function populate_lingerie_category_checkbox($form){
    //get all the lingerie-categories
	$terms = get_terms('lingerie-categories', 'orderby=name&hide_empty=false');

	//Creating choices and inputs as empty arrays
    $choices = array();
    $inputs = array();

	$i = 1;
	foreach( $terms as $term ):
		$field_id = "31.".$i;
		array_push($choices, array("text" => $term->name, "value" => $term->name));
		array_push($inputs, array("label" => $term->name, "id" => $field_id));
	$i++;
	endforeach;

	// we need a counter to create the field id
	//Adding items to field id 31
   	foreach($form["fields"] as &$field):

        if($field["id"] == 31):

			$field["type"] = 'checkbox';
            $field["choices"] = $choices;
       	    $field["inputs"] = $inputs;

   	    endif;

	endforeach;	

    return $form;
}//end populate_lingerie_category_checkbox

With this I am changing a text input into a set of checkboxes. Not sure if this is the correct way to go about it. I do this for all of the taxonomies with separate functions for each text field to change/alter.

I get no notice and no email is sent. I really am at a loss here. Any help is greatly appreciated!

No unfortunately it doesn't. Tried that after I submitted to the forums. I also created a another new form, just a small one, and it worked. It had 4 form fields. Thanks

Sorry for all the extra postings here. Should have done a search before hand.

Found info on how to do this without adding a bunch of extra hook functions. Multiple forms that redirect to the next page in the set of forms. Only question is: do I add CAPTCHA on each page/form to limit spamming across the 9 pages of forms I need to use?
