onChange!!

Jeg vil gerne af med mine knapper i denne kode, kan nogen hjælpe mig. Jeg har aldrig programmeret javascript før så et beskrivende svar ville være dejligt.

<SELECT NAME="list">
<?
require_once("functionsFdc.php");
get_tabelname();
?>
</SELECT>
<INPUT TYPE="submit" VALUE="OK" Name="getList">
</td
</tr>
<tr>
<td>Artikelnummer:</td>
<td><select name="artNrlist">
<?
if (isset($_POST["getList"]))
{
$list = $_REQUEST["list"];
require_once("functionsFdc.php");
UdfyldDropDownBox($list);
}
?>
</select>
<INPUT TYPE="submit" VALUE="OK" Name="get_info">
</td>
</tr>
<tr>
<td>Kg/kartong:</td>
<td><input type="text" size="10" maxlength="100" name="antalkg" <? if (isset($_POST["get_info"])) { ?>value="<? $list = $_REQUEST['list'];$artNrlist = $_REQUEST['artNrlist'];require_once('functionsFdc.php');get_antal($list,$artNrlist); } ?>" style="font:100 12 Verdana;border-width:1;background-color:#fafaf0;color:#0000ff"></td>
</tr>
