Dynamically Populating a Custom Field Drop Down

Hi, I have extended user registration fields using Cimmy User Extra Fields plugin and added a dropdown box of a list of companies.

What I need to do is to insert the same field into a GF form by pre populating the data from the wp_cimy_uef_fields MySQL table where Cimmy plugin has stored the information.

Been searching forum and documentation but can't seem to find a solution. Is this possible and how do I go about doing it if yes.

Hi, I have the drop down values in an array (Company A, Company B, Company C, Others). I tried to make use of the gform_pre_render but I'm not really good at it. The result I got was a drop down list with only 1 item ie Company A, Company B, Company C, Others instead of it being 4 items in the list. Please help. (Source code below)

function populate_dropdown($form){

  $con = mysql_connect("localhost","root","");
  if (!$con)
    {
    die('Could not connect: ' . mysql_error());
    }

  mysql_select_db("asm", $con);

  $result = mysql_query("SELECT * FROM <code>wp_cimy_uef_fields</code> WHERE ID = '1'");
  $label = mysql_fetch_assoc($result);
  $company = array();
  $company = $label[LABEL];

  $items = array();
  $items[] = array("text" => "", "value" => "");

  $items[] = array("text" => $company, "value" => $company);

  foreach($form["fields"] as &$field)
        if($field["id"] == 18){
            $field["choices"] = $items;
        }
  return $form;
