    Hello nice peoples. I have this form that has me puzzled(what me no way).
    It works(with needless warnings) if I submit it twice. I know it's a lot
    but can you see my error?
    -------------------------------------------------
    this is code:

    <!DOCTYPE HTML><html>
<head>

<style>
.error {color: #FF0000;}
</style>

</head>
<body bgcolor="ccffff"><center><b> 

<?php
echo "<center>";echo date('m/d/y');echo "</center>";

// define variables and set to empty values
$tenantErr = $unitErr = $rentpaidErr = $datepaidErr = $commentErr = "";
$tenant = $unit = $rentpaid = $hudpay = $datepaid = $comment = "";

if ($_SERVER["REQUEST_METHOD"] == "POST")
{

  if (empty($_POST["tenant"])) { $tenantErr = "tenant is required"; }
else {
  $tenant = test_input($_POST["tenant"]);
  // check if tenant only contains letters and whitespace
  if (!preg_match("/^[a-zA-Z-' ]*$/",$tenant)) {
  $tenantErr = "Only letters and white space allowed"; }
  }
}

  if (empty($_POST["unit"])) {
  $unitErr = "unit is required";
  }
else {
  $unit = test_input($_POST["unit"]);
  // check if unit only contains letters and whitespace
  if (!preg_match("/^[a-zA-Z-' ]*$/",$unit)) {
  $unitErr = "Only letters and white space allowed";
  }
  }
  
  if (empty($_POST["rentpaid"])) {
  $rentpaidErr = "rentpaid is required";
  }
else {
  $rentpaid = test_input($_POST["rentpaid"]);
  // check if rentpaid only contains letters and whitespace
  if (!preg_match("/^[a-zA-Z-' ]*$/",$rentpaid)) {
  $rentpaidErr = "Only letters and white space allowed";
  }
  }

if (empty($_POST["hudpay"])) {
  $hudpayErr = "hudpay is required";
  }
else {
  $hudpay = test_input($_POST["hudpay"]);
  // check if hudpay only contains letters and whitespace
  if (!preg_match("/^[a-zA-Z-' ]*$/",$hudpay)) {
  $hudpayErr = "Only letters and white space allowed"; 
  }
  }

if (empty($_POST["datepaid"])) {
  $datepaidErr = "datepaid is required";
  }
else {
  $datepaid = test_input($_POST["datepaid"]);
  // check if datepaid only contains letters and whitespace
  if (!preg_match("/^[a-zA-Z-' ]*$/",$datepaid)) {
  $datepaidErr = "Only letters and white space allowed"; 
  }
  }


if (empty($_POST["comment"])) {
  $comment = "";
  }
else {
  $comment = test_input($_POST["comment"]);
  }

function test_input($data) {
  $data = trim($data);
  $data = stripslashes($data);
  $data = htmlspecialchars($data);
  return $data;
}
?>

    Hey, try this code. I added the definition of this ($hudpayErr) variable at the beginning. If there are any more problems with the code, I am happy to help.

    <!DOCTYPE HTML><html>
<head>

<style>
.error {color: #FF0000;}
</style>

</head>
<body bgcolor="ccffff"><center><b>

<?php
echo "<center>" . date('m/d/y') . "</center>";

// define variables and set to empty values
$tenantErr = $unitErr = $rentpaidErr = $datepaidErr = $commentErr = $hudpayErr = "";
$tenant = $unit = $rentpaid = $hudpay = $datepaid = $comment = "";

if ($_SERVER["REQUEST_METHOD"] == "POST")
{

    if (empty($_POST["tenant"]))
    {
        $tenantErr = "tenant is required";
    }
    else
    {
        $tenant = test_input($_POST["tenant"]);
        // check if tenant only contains letters and whitespace
        if (!preg_match("/^[a-zA-Z-' ]*$/", $tenant))
        {
            $tenantErr = "Only letters and white space allowed";
        }
    }
}

if (empty($_POST["unit"]))
{
    $unitErr = "unit is required";
}
else
{
    $unit = test_input($_POST["unit"]);
    // check if unit only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z-' ]*$/", $unit))
    {
        $unitErr = "Only letters and white space allowed";
    }
}

if (empty($_POST["rentpaid"]))
{
    $rentpaidErr = "rentpaid is required";
}
else
{
    $rentpaid = test_input($_POST["rentpaid"]);
    // check if rentpaid only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z-' ]*$/", $rentpaid))
    {
        $rentpaidErr = "Only letters and white space allowed";
    }
}

if (empty($_POST["hudpay"]))
{
    $hudpayErr = "hudpay is required";
}
else
{
    $hudpay = test_input($_POST["hudpay"]);
    // check if hudpay only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z-' ]*$/", $hudpay))
    {
        $hudpayErr = "Only letters and white space allowed";

    $datepaidErr = "datepaid is required";

    $datepaid = test_input($_POST["datepaid"]);
    // check if datepaid only contains letters and whitespace
    if (!preg_match("/^[a-zA-Z-' ]*$/", $datepaid))
    {
        $datepaidErr = "Only letters and white space allowed";
    }
}

if (empty($_POST["comment"]))
{
    $comment = "";
}
else
{
    $comment = test_input($_POST["comment"]);
}

function test_input($data)
{
    $data = trim($data);
    $data = stripslashes($data);
    $data = htmlspecialchars($data);
    return $data;
}
?>
