# multiple a single variable

I have a set rental amount with some variable making an equation. The final variable is the TOTAL of all the equations, i need the total of this variable

[php]<?php //option 1 52 weeks
\$weeklyToStudent = \$row_rsTenProp[‘rental_price’];
\$fourWeeksSecurityDep = 4 * \$weeklyToStudent;
\$fivetwoWeeksPayable = \$weeklyToStudent * 52;
\$fee = 184.80;
\$resFee = 250;
\$fivetwoPayIncFeedSecDep = \$fourWeeksSecurityDep + \$fivetwoWeeksPayable + \$fee;
\$initPay15Wks = \$weeklyToStudent*15;
\$initPay15WksFeeSecDep = \$initPay15Wks + \$fee + \$fourWeeksSecurityDep;
\$balanceB4MovingIn = \$initPay15WksFeeSecDep - \$resFee;
\$second14Wks = \$weeklyToStudent * 14;
\$third14Wks = \$weeklyToStudent * 14;
\$fourth9Wks = \$weeklyToStudent * 9;
\$totalPayment = \$initPay15WksFeeSecDep + \$second14Wks + \$third14Wks + \$fourth9Wks;
?>
<?php do { ?>

<?php echo \$row_rsTenProp['userid']; ?>
<?php echo \$row_rsTenProp['weeks'] / 7; ?> weeks
<?php echo \$row_rsTenProp['payment_option']; ?>
<?php echo \$row_rsTenProp['rental_price']; ?>
<?php echo \$row_rsTenProp['prop_id']; ?>
``````            <td class="table-text"><?php echo DoFormatCurrency(\$totalPayment, 2, ',', '.', '£ '); ?></td>
<td> </td>
<td> </td>
</tr>
<?php
} while (\$row_rsTenProp = mysql_fetch_assoc(\$rsTenProp)); ?>[/php]
``````

i need to multiple the \$totalPayment to get the TOTAL of this variable

[php]<?php
\$totalPaymentTot = 0;
while
(\$totalPaymentTot = (\$totalPayment));
\$totalPayment += \$totalPayment;{
\$row_totalPayment;
}
echo \$totalPaymentTot;?>[/php]
