Mysql PHP Need Help

Hi,

I need some help. I have data in a table (cust) and one of the columns has multiple values in it (cat_id). I need to use those values to select data (cat_name) from a second table (cat) and display this with the data from the first table where (cat_id) are the same. The data is writen into (cust) in an area that is serialize then unserialize. Thanks in advance.

<table width="100%" border="0" align="center" cellpadding="4" cellspacing="4">
  <tr> 
    <td bordercolor="#000000" bgcolor="#F4F4F4"> 
      <?php
$i=0;
while ($i < $num) {
$f1=mysql_result($result,$i,"fname");
$f2=mysql_result($result,$i,"lname");
$f3=mysql_result($result,$i,"address");
$f4=mysql_result($result,$i,"city");
$f14=mysql_result($result,$i,"state");
$f5=mysql_result($result,$i,"zip");
$f6=mysql_result($result,$i,"phone");
$f7=mysql_result($result,$i,"fax");
$f8=mysql_result($result,$i,"email");
$f10=mysql_result($result,$i,"website");
$f11=mysql_result($result,$i,"comments");
$f12=mysql_result($result,$i,"cat_id");
$f12=unserialize($f12);
$f12 = implode(",",$f12);
$f13=mysql_result($result,$i,"cust_id");
$f15=mysql_result($result,$i,"area_id");

?>
<?php 
$query2=" SELECT * FROM category WHERE cat_id IN ('$f12')";
$result2=mysql_query($query2) or die(mysql_error());;
$row = mysql_fetch_array($result2);
mysql_close();

$f16=mysql_result($result2,$i2,"cat_name");

?>

<?php 
$query3=" SELECT * FROM area WHERE area_id=$f15";
