Hello everything,
I am not uderstanding what i did wrong. Everything looks good but before they submit the information it should ask to re-enter the password. Can someone help me out to understand this. Here is my code

<?php
function showForm($strMessage){
  echo "<h1>".$strMessage."</h1>";
  echo " <p>Note: fields marked with '*' are required</p>\n";
  echo "<form action=\"".$_SERVER['PHP_SELF']."\" method=\"post\">\n";
  echo "<table width=\"45%\" class=\"formtable\" cellpadding=\"3\" cellspacing=\"0\">\n";
  echo "	<tr>\n";
  echo "		<td><span id=\"rfvname\">* Name:</span></td>\n";
  echo "		<td><input type=\"text\" name=\"name\" value=\"".$_POST['name']."\" /></td>\n";
  echo "	</tr>\n";
  echo "    <tr>\n";
  echo "		<td><span id=\"rfvemail\">* E-mail:</span></td>\n";
  echo "		<td><input type=\"text\" name=\"email\" value=\"".$_POST['emial']."\" /></td>\n";
  echo "	</tr>\n";
  echo "      <tr>\n";
  echo "		<td><span id=\"rfvusername\">* Username:</span></td>\n";
  echo "		<td><input type=\"text\" name=\"username\" value=\"".$_POST['username']."\" /></td>\n";
  echo "	</tr>\n";
  echo "	<tr>\n";
  echo "		  <td><span id=\"rfvpword\">* Password:</span></td>\n";
  echo "		  <td><input type=\"password\" name=\"pword\" value=\"".$_POST['pword']."\" /><br /><span style=\"font-size:9px;\"><em>(at least 4 chars)</em></span></td>\n";
  echo "	</tr>\n";
  echo "    <tr>\n";
  echo "		<td><span id=\"rfvpword\">* Re-enter Password:</span></td>\n";
  echo "		<td><input type=\"text\" name=\"pword\" value=\"".$_POST['pword']."\" /></td>\n";
  echo "	</tr>\n";
  echo "	<tr>\n";
  echo "		   <td>&nbsp;</td>\n";
  echo "		   <td><input type=\"submit\" value=\"Submit\" class=\"btnSubmit\" id=\"btnSubmit\" name=\"submit\" /></td>\n";
  echo "	</tr>\n";
  echo "</table>\n";
  echo "</form>\n";
}
?>

	}
	else{
		$strMessage= "Please fill out the form below to send your information:";
		showForm($strMessage);
	}
?>

why are you pasting post values (possibly non-existent) to the form?

Also not a good idea to echo out the cleartext password.
