I need help with dynamic forms and php

Can anyone help?

I developed a littl code using php html and java to try and provide a dynamic drop down list on the page

my java fuctions are as :
<SCRIPT language=JavaScript>
function reload(form)
{
var val=form.season.options[form.season.options.selectedIndex].value;
self.location="team.php?season="+val ;
}
function reload2(form)
{

var val=form.team.options[form.team.options.selectedIndex].value;
var mylocate ="team.php?team="+val;
self.location= mylocate ;
}
</script>

the PHP?HTML

// ##### Select Team #####
<p class=\"main\" align = center>select a Team
<?php
echo "<select name = \"team\" onChange=\"reload2(this.form)\">";

if ($getteam == "All") {
ECHO "<option selected value = \"All\">All</option>";
}
else
{
ECHO "<option >All</option>";
}
foreach ($teamarray as $teamout) {
if ($getteam == $teamout) {
ECHO "<option selected value = \"$teamout\">$teamout</option>";
}
else
{
echo "<option> $teamout</option>";
}
}
echo "</select>";
?>
</p>

this works with fine under fire fox using
@$cseason =$HTTP_GET_VARS['season'];
@$cteam = $HTTP_GET_VARS['team'];

to return the variables for refreshin my sql read. unfortunately under internet explorer it doesn't return the value therfore my script doesnt work.
