Insert into help

Im currently working on some code that queries a db and pulls several fields and inserts them into another db. However Im running into an issue where it isnt inputting into a specific field (tracs) but it pulls the rest.

$run = mysql_query($query);
while ($row = mysql_fetch_array($run))
{
if($row[TRACS] !=='')
                {
include_once 'db2.php';
$sql="INSERT INTO data (number, market, tracs, status, date)
VALUES
('$row[caller]','$row[market]','$row[TRACS]','active','$tdy')";
 
if (!mysql_query($sql))
  {
  die('Error: ' . mysql_error());
  }
}

Any thoughts? The output is looking something like this.

id number market tracs status date Edit Delete
