Hello. I've been having trouble with this trade system not working(my friend made it). Most of it is functioning properly, except the part where it's supposed to show your partners pokemon box. Here is the code:

<?php

require_once("top_header.php");

if(!isset($_GET["p"]) && !isset($_GET["id"]) && !isset($_GET["submit"])) {

?>

      <form action="trading.php" method="get">

        Please enter the ID of the person you would like to trade:<br />

        <input type="text" name="p" /><br />

        <input type="submit" value="Continue!" /><br />

      </form>	  

	  <table width=100%>

	            <tr>

            <td class="header">Trade Partners:</td>

            <td class="header">Open Trades:</td>

          </tr>

<?php

$check1 = "SELECT trade_id, starter_id FROM trades WHERE partner_id = $id AND status = 0";

$check2 = mysql_query($check1);

while($row = mysql_fetch_array($check2)) {

$ass = mysql_fetch_array(mysql_query("SELECT username FROM users WHERE id = {$row["starter_id"]}"));

echo "<tr>";

echo "<td class=into>";

echo $ass["username"];

echo "</td>";

echo "<td class=into>";

echo "<a href=trading.php?id={$row["trade_id"]}>View Trade!</a>";

echo "</td>";

echo "</tr>";

}

?>

<tr>

            <td class="header">Created To:</td>

            <td class="header">Options:</td>

          </tr>

<?php

$check1 = "SELECT trade_id, partner_id FROM trades WHERE starter_id = $id AND status = 0";

$check2 = mysql_query($check1);

while($row = mysql_fetch_array($check2)) {

$ass = mysql_fetch_array(mysql_query("SELECT username FROM users WHERE id = {$row["partner_id"]}"));

echo "<tr>";

echo "<td class=into>";

echo $ass["username"];

echo "</td>";

echo "<td class=into>";

echo "<a href=delete.php?id={$row["trade_id"]}>Delete Trade!</a>";

echo "</td>";

echo "</tr>";

}

?>

</table>

<?php

} else if(isset($_GET["p"])) {
$check = mysql_num_rows(mysql_query("SELECT username FROM users WHERE id = ".$_GET['p'].""));
if($check <= 0)
{
echo "Please do not try to trade non existant users!";
include('bottom_layout.php');
die();
}

?>

  <form action="trading.php?submit" method="post">

  <b>Your Pokemon:</b><br>

    <select width="100px" size=15 name="starter[]" multiple="multiple">

A description of your problem is generally helpful.

Forgive me, I thought I put it in there. xD

 

Well, the issue seems to be that when I'm trading with someone, their pokemon box is empty, when it isn't supposed to be. Your pokemon works fine, and lists the pokemon in your box, but where it's supposed to print out the person's box of whom your trading with, it just shows None(which is an option).
