何が起こっているのかを調べるのを手伝ってくれる専門家はいますか?

代码如下:
function amortizationTable($pNum,$periodicPayment,$balance,$monthlyInterest)
{
$paymentInterest=round ($balance*$monthlyInterest,2);
$paymentPrincipal=round ($periodicPayment-$paymentInterest ,2);
$newBalance=round ($balance-$paymentPrincipal,2);
if ($newbalance < $paymentPrincipal){
$newBalance=0;
}

printf("%d",$pNum );
printf("$%S",number_format($newBalance,2));
printf("$%S",number_format ($periodicPayment,2));
printf("$%S",number_format($paymentPrincipal,2));
printf("$%S< /td>",number_format($paymentInterest,2));
if($newBalance>0){
$pNum++;
amortizationTable($pNum,$periodicPayment,$newBalance, $monthlyInterest);
}else{
return 0;
}
}
$balance=10000.00;
$interestRate=.0575;
$monthlyInterest=$interestRate/ 12;
$termLength=5;
$paymentsPer Year=12;
$paymentNumber=1;
$totalPayments=$termLength*$paymentsPer Year;
$intCalc=1 + $interestRate/$ paymentPer Year;
$periodicPayment=$balance*pow($intCalc,$totalPayments)*($intCalc-1)/(pow($intCalc,$totalPayments)-1);
$periodicPayment=round($periodicPayment ,2);
echo"";
echo"
;";
aomrtizationTable($paymentNumber,$periodicPayment,$balance,$monthlyInterest);
echo"

支払い番号< ;/th>	残高	支払い	元金	利息

";
?>
の結果は次のとおりです。

致命的エラー: C:AppServwwwtest.php の 38 行目で未定義関数 aomrtizationTable() を呼び出します
支払い番号残高支払い元本利息

---- --解決策-------------------

aomrtizationTable($paymentNumber,$periodicPayment,$balance,$monthlyInterest);amo 。 .. 不是 aom
