Capturing the selected value

[aggiefan]

I have the following code in my php file. The code creates a dropdown in my template of all the teams in the vbcontest_teams_ncaafootball database. I want it to capture the selected team and write it to a different table in the database. If I include the write to db part inside the while loop -- it writes all 12 options (so you can't tell what was selected. If you put it outside of the while loop, it writes a blank. Any ideas on what needs to be there to capture the selected value in the dropdown? See the screenshot if it helps you visualize it.

if ($_GET['action'] == "createweek")  {
 
$query_teams=$vbulletin->db->query('select team_name from ' . TABLE_PREFIX . 'vbcontest_teams_ncaafootball'); 
 $teams='';
 while($tea=$vbulletin->db->fetch_array($query_teams)){
 $selected='';
 if(@$_REQUEST['team_name']==$tea['team_name'])
 $selected=' selected';
 $teams.="<option value=\\\"".$tea['team_name']."\\\"$selected>".$tea['team_name']."</option>";
 
$errormessage = "<center>Congratulations!  You have successfully created your contest.  You can now advance to creating weeks.  Click below to begin or use the navigation in the adminCP.<br><br><a href=/forums/admincp/contestv2admin2.php?action=createweek>Click here to continue on and create a week for your contest</a href>";
$answerall = true;
}
if ($_POST['action'] == "submit") {
  if ($num == '5)
  {
     $errormessage = "$vbulletin->userinfo[username], you have 5 contests in the database already.  Please delete one before continuing.  Maintaining your contests will provide for quicker queries and better results for your users.";
  eval('print_output("' . fetch_template('STANDARD_ERROR') . '");');
     exit();
  } 
 eval('$formsend = "' . fetch_template('vBContestanswers') . '";');
$db->query_write("INSERT INTO " . TABLE_PREFIX . "vbcontest_teams_ncaafootball (`team_name`) VALUES ('\\\"".$tea['team_name']."\\\"$selected')");
 
}
