[RESOLVED] SQL query not responding correctly

[Jazz00006]

heres my code:

$sql ="UPDATE `smf_members` SET 
`Quote1` = '" . $_POST['Quote1'] . "',
`Quote2` = '" . $_POST['Quote2'] . "',
`Quote3` = '" . $_POST['Quote3'] . "' WHERE `ID_MEMBER` =" . $_GET['user'] . " LIMIT 1 ;"; 

<form action="http://sf.greyfyre.info/roed/changequote.php?C=1&user=<?php echo $_GET['user']; ?>" method="post" name="form1" id="form1">
  <label>Quote1
  <input name="Quote1" type="text" id="Quote1" value="<?php
mysql_close($sql);
echo $data['Quote1'];
  ?>
  " size="40" maxlength="30" />
 
    <label>Quote2
    <input name="Quote2" type="text" id="Quote2" value="<?php
echo $data['Quote2'];
  ?>" size="40" maxlength="30" />

    <label>Quote3
    <input name="Quote3" type="text" id="Quote3" value="<?php
echo $data['Quote3'];
  ?>" size="40" maxlength="30" />
    </label>
  </p>


            <label>Password
            <input name="password" type="password" id="password" />
            </label>

                    <input type="submit" name="Submit" value="Submit" /></p>

</form>

and heres my problem, some times the code will update a database, and sometimes it will only change quote3, is it something i am not doing right? (probably is but i thought i would come here first because im still learning php)
