You need to populate the cells with content.  Typically this requires server-side scripting.  What language are you using to process your form input on the server?

you should echo your variables in input fields like
<input type="text" name="some_name" value="<?php echo $some_name ?>">

The data in your form will arrive in the action script in an associative array called $_POST.  Please abide by all the usual caveats about filtering input - you MUST NOT trust the contents of $_POST.  There are bad guys out there on the internet who will destroy your data base just for fun if you don't filter the input.

That said, here is a general example:
<?php // RAY_post.php

if ($_POST["instring"] != '') {

	extract ($_POST);

	echo "<br />You posted $instring \n";

}

?>
 

<form method="post" action="<?=$PHP_SELF?>">

<br />Post here:<input type="text" name="instring" value="<?=$instring?>" />

<input type="submit" value="Go" />

</form>

$field1 = $_POST['field1'] ;
<input type="text" name="field1" value="<?php echo $field1 ?>">

        The logic in here is that ; when you post the page all of the inputs will be send to post array with their names and you can reffer them by thier names like ; $_POST['type_input_name_here'] ;
      May be it might help you to understand it better if you first try to test it with a string instead of variable like ;
    <input type="text" name="field1" value="Field 1 value goes here">
    The statment above will write Field1 value goes here text inside the inputbox if you test it.
     
    So that means we can dynamically print our variable in there as i wrote above...

If you send your code it would be easier to debug, but generally the form should look like that ;
##################some.php#################### <<< The file name that you should save as..
<form action="some.php" method="post">
<input type="text" name="field1" value="<?php echo $_POST['field1'] ?>">
<input type="submit" value="send">
</form>

    In first time that you call page ,there wont be any values inside field1 as we know, whenever you type something in field1 and click submit it should echo the value...

milionnzaru: The code I posted runs.  You can see it in action here: http://www.laprbass.com/RAY_post.php

What language are you using in your action script?  Is it PHP?  Please post the action script.

If the echo() command does not work, there is something seriously wrong with your installation of PHP!!

Standing by, ~Ray
