  <?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";

Well the echo’s and the ” and \ is how I have to set this all up. So it is suppose to look like that. And all i am asking is if someone can help me understand how to do the error code. Not to do it for me but help me understand it. Is the code i already started on will it work or am I doing it all messed up. And thank to whoever is voting me down.I am just asking a simple question.

    Your problem is this:

     $_REQUEST["RE-enter Password"]

    You used the textual label for the form fields. But your actual input field is called:

     $_REQUEST["repword"]

    Likewise for all the other fields. The $_REQUEST array holds the keys according to the name= attributes in the HTML form.

    Something else: You can also simplify the form output. Instead of the many echos you should use a heredoc string to avoid the many " dquotes and \ backslash escapes:

    echo <<<HTML
 <h1>$strMessage</h1>
 <p>Note: fields marked with '*' are required</p>
 <form action="$_SERVER[PHP_SELF]" method="post">
 <table ...
      <td><span id="rfvname">* Name:</span></td>
     <td><input type="text" name="name"   value="$_POST[name]"></td>
 ...
HTML;

    Also add $_POST = array_map("htmlentities", $_POST); before that (for simplicity/security).
