Pause and Run button in PHP script - HELP

Hi guys!
I need a little help in PHP. I need to put into the PHP code functions which will insert to mysql database "jobs" STATUS=2 for Pause button and STATUS=1 for Run button

CODE:

<?php
include("include/header.php");
if(!isset($_SESSION["userlogin"])) { header("location: login.php"); exit(); }
$edit=dbFetchArray(dbQuery("select * from `user_registration` where `email`='".$_SESSION["userlogin"]."'"),MYSQL_BOTH);
$Id=base64_decode($_REQUEST['Id']);
$up=mysql_fetch_array(mysql_query("select * from `jobs` where `id`='".$Id."'"));
$status=stripslashes($up["highlighted"]);
$name=stripslashes($up["title"]);
$explode=explode(" ",$name);
$tit=isset($explode[0])?$explode[0]:'';
$col=isset($explode[1])?$explode[1]:'';
$cat=isset($explode[2])?$explode[2]:'';

$user=mysql_fetch_array(mysql_query("select * from `user_registration` where `email`='".$_SESSION["userlogin"]."'"));
$fullname=stripslashes($user['fullname']);
$customer_id=$user['id'];
$current_balence=$user['current_balance'];

if(isset($_POST["Button"])) {
    if(isset($_REQUEST["Available_positions"]))
    {
    $Available_positions=$_POST["Available_positions"];
    if(strpos($Available_positions,'.')===false) {
    $pos=$Available_positions;
    $pos1=0;
    } else {
    $pieces = explode(".", $Available_positions);
    $pos=$pieces[0];
    $pos1=$pieces[1];
    }

    $Payment_per_task=$_POST["Payment_per_task"];

    $hid=$_REQUEST['hid'];
    if($pos1>0)
    {
    ?>
    <script>
    alert('Job Posting Suspended');
    window.location.href="edit_job.php?Id=<?=base64_decode($hid)?>";
    </script>
    <?
    }
    else
    {
    dbQuery("update `jobs` set `wd2`='".$Available_positions."',`price`='".$Payment_per_task."' where `id`='".$hid."' and `email`='".$_SESSION["userlogin"]."'");
    ?>
    <script>
    window.location.href="employer.php";
    </script>
    <?
    }
    }
    $_SESSION['hid']=$hid;
    if($hid>0) {
    $_SESSION["success"]='';
    } else {
    $_SESSION["error"]='';
    }
} else if(isset($_POST["Cancel"])) {
$hid=$_REQUEST['hid'];
dbQuery("update `jobs` set `status`='3' where `id`='".$hid."' and `email`='".$_SESSION["userlogin"]."'");
$resJ=dbFetchArray(dbQuery("select * from `jobs` where `id`='".$hid."' and `email`='".$_SESSION["userlogin"]."'"),MYSQL_BOTH);

if($resJ["wd1"]!=$resJ["wd2"]) {
$CJ= $resJ["wd2"] - $resJ["wd1"];
$CJFees = $CJ*$resJ["price"];
dbQuery("insert into `myaccount`(`email`,`amount`,`type`,`createdate`,`jobid`) values('".$_SESSION['userlogin']."','$CJFees','10',NOW(),'".$resJ["id"]."')");
$rescurbal=dbFetchArray(dbQuery("select * from `user_registration` where `email`='".$_SESSION['userlogin']."'"),MYSQL_BOTH);
dbQuery("update `user_registration` set `current_balance`='".($rescurbal["current_balance"]+$CJFees)."' where `email`='".$_SESSION['userlogin']."'");
}
?>
<script>
window.location.href="employer.php";
</script>
<?
}
?>

PHP:

...
and button code:
...

<br><input type="submit" value="Submit Campaign" <?php if($up["status"]=='3') { echo 'disabled="disabled"';} ?> name="Button">&nbsp;&nbsp;<input type="submit" value="Finished Campaign" <?php if($up["status"]=='3') { echo 'disabled="disabled"';} ?>  name="Cancel"><br />

Code (markup):

I tried to do that, but I always get some error. Please help!
