Custom fields not posting properly « Gravity Support Forums

I have built a few custom fields that have multiple inputs (First, Middle, Last, Maiden Names). It is displaying properly, and as far as I can tell the naming convention looks right...however when the form is submitted the values in the fields are not being posted. I noticed that in the $form that I got from the gform_post_submission hook, that the input for the fields was empty, while the stock form[fields][inputs] pieces all had arrays listing the different input pieces within the field. What do I need to do so that the input will properly update with the fields I want in it?

See below for the current html of how my custom field is being put into the page.
Thanks in advance for any help!

Edit: Additional Info:
To put my custom field into the interface I use gform_add_field_buttons to put it in, gform_field_type_title to give it a title and gform_field_input to modify what it looks like. For the gform_field_input function all I do is create the HTML, based on the current form id and the id of the field to build the id's and names of all the html tags.

<div class="ginput_complex ginput_container" id="input_3_3_3">
   <span id="input_3_3_3_container">
      <input type="text" name="input_3.3" id="input_3_3_3" value="test">
      <label for="input_3_3_3"> First </label>
   </span> 

   <span id="input_3_3_6_container">
      <input type="text" name="input_3.6" id="input_3_3_6" value="">
        <label for="input_3_3_6"> MI </label>
   </span>

   <span id="input_3_3_9_container">
      <input type="text" name="input_3.9" id="input_3_3_9">
      <label for="input_3_3_9"> Last </label>
   </span>
   <span id="input_3_3_12_container">
      <input type="text" name="input_3.12" id="input_3_3_12">
      <label for="input_3_3_12"> Maiden </label>
   </span>
</div>
