List box errors

[SFDonovan]

In my table I have two divisions. Axis and Allied div_id = 1 and div_id = 2.

I have a script the has a list box that displays all teams from the opposing div_id meaning it displays all teams != to your div_id.

The problem is when I select one of the opposing teams in the list box the only team_id that gets written to the table is the last one.

First I find my current div_id based on my username on the site and if it is listed as a commander.

//Find the value of the division ID. 
  $nukeusername = $userinfo['username'];  

  $sql = "SELECT div_id FROM " . $prefix . "_eto_divisions 
  WHERE (div_commander ='$nukeusername' || div_xo ='$nukeusername')";  

  $result = $db->sql_query($sql);  

  $mydiv = $db->sql_fetchrow($result);
  $div_id = $mydiv[div_id]; 

Then I filter the values of the teams I want to display.

//Filter the values for the list box.
$result = $db->sql_query("SELECT * FROM " . $prefix . "_tc_ladderteams tclt
LEFT JOIN " . $prefix . "_tc_teams tct ON (tclt.team_id = tct.team_id)
LEFT JOIN " . $prefix . "_eto_campaigns ec ON (tclt.ladder_id = ec.cid)
LEFT JOIN " . $prefix . "_tc_ladders tcl ON (tcl.sid = tclt.ladder_id)
WHERE tct.div_id != $div_id 
AND tcl.active = 1
AND tct.is_active = 1");

Then I show my list box.

while ( $row = $db->sql_fetchrow($result) ) {
	$dteam_name = $row["name"];
	$dteam_id = $row["team_id"];
echo "<option value='$dteam_id'>$dteam_name</option>";

}
echo "</select>";// Closing of list box 

I may have 8 or 10 teams signed up as Axis but no matter who I choose in the list box the only team_id that gets wriiten is the very last team_id for the Axis. team_id = 153

I'm confused.
