comparing problem

[Irlan agous]

The problem is like this, There are a number of $rows resulting from the
query described below. There is a variable named payment, this has for
example the vualue 2. lets say the query had 5 results, the i want to do a
compare that it shows only 2, depending on the value of $payment

Can someone help me?

$query = "SELECT a.oproep,b.oproep, a.react, b.react, a.logid, b.logid,
a.persid,b.persid, a.logemail, b.logemail,a.persemail,b.persemail

FROM reactie a, reactie b
WHERE a.logid = b.persid AND b.logid = a.persid AND a.logid='$logid' ";
$result = mysql_query($query);

$query_data = mysql_fetch_row($result);// Haal de gegevens uit de tabel
if($result = mysql_query($query)){
$rows = mysql_num_rows($result);

if($rows<1){
echo "<p>You have no Matches";

} else {
echo "<p>You have $rows Match(es)<p><p>";
}}
while($query_data = mysql_fetch_array($result)){
$oproep = $query_data["oproep"];
$persid = $query_data["logid"];
$reactie = $query_data["react"];
$logemail = $query_data["logemail"];

echo " <tr>\n";
echo " <td align=center bgcolor=FFECC4 ><font
color=black><a
href=\"javascript:Pop550Picture('../pic/klanten/gegevens.php?id=$persid')\"><p>$oproep</a></td>\n";//

echo " <td align=center bgcolor=FFECC4 ><font
color=black><p>".$reactie."</td>\n";
echo " <td align=center bgcolor=FFECC4 ><font
color=black><p>".$reactie."</td>\n";
echo " <td align=center bgcolor=FFECC4 ><font
