Update modified timestamp in Dreamweaver and MySQL PHP database

Hello experts!  I have an update page where I want the current timestamp updated in the database when the user presses the submit button.  I have the update page and it's working (thanks to another expert in the Dreamweaver area).  I have a hidden field that is set to update field [modified] in the database table.

My question is what do I put in the hidden field (called hiddenmodified) in the Value field?  I'm trying now() and timestamp() but it's not working.

On the update record behavior I am telling Dreamweaver that this field is to update to [modified] field in database but I think I'm just not knowing what to put there in the Value field of the hidden field on my form.

In my table structure I have this set to timestamp.
Thank you experts!

Partial code below showing hidden form field with current value:

<form action="<?php echo $editFormAction; ?>" id="form1" name="form1" method="POST">
  <table width="100%" border="1" cellpadding="2" cellspacing="2">
    <tr>
      <td>ID:</td>
      <td><label for="ID"></label>
        <?php echo $row_Recordset1['ID']; ?></td>
    </tr>
    <tr>
      <td width="22%">Date Added:
      <input name="hiddenmodified" type="hidden" id="hiddenmodified" value="CURRENT_TIMESTAMP" />
      <input name="ID" type="hidden" id="ID" value="<?php echo $row_Recordset1['ID']; ?>" /></td>
      <td width="78%"><label for="dateadded"></label>
        <?php echo $row_Recordset1['Date_Added']; ?></td>
    </tr>
    <tr>
      <td>Date Last Modified:</td>
      <td><label for="datemodified"></label>
        <?php echo $row_Recordset1['Modified']; ?></td>

The rest of my update query here...
if ((isset($_POST["MM_update"])) && ($_POST["MM_update"] == "form1")) {
  $updateSQL = sprintf("UPDATE tblInfo SET Modified=%s, Bus_Name=%s, Contact_Name=%s, Address=%s, City=%s, `State`=%s, Zip=%s, Phone=%s, Fax=%s, Email=%s, Website=%s, Active=%s, Bus_Month=%s, Bus_Year=%s, Comments=%s WHERE ID=%s",
                       GetSQLValueString($_POST['hiddenmodified'], "date"),
                       GetSQLValueString($_POST['busname'], "text"),
                       GetSQLValueString($_POST['contactname'], "text"),
                       GetSQLValueString($_POST['address'], "text"),
                       GetSQLValueString($_POST['city'], "text"),
                       GetSQLValueString($_POST['state'], "text"),
                       GetSQLValueString($_POST['zip'], "text"),
                       GetSQLValueString($_POST['phone'], "text"),
                       GetSQLValueString($_POST['fax'], "text"),
                       GetSQLValueString($_POST['email'], "text"),
                       GetSQLValueString($_POST['website'], "text"),
                       GetSQLValueString($_POST['status'], "int"),
                       GetSQLValueString($_POST['bommonth'], "text"),
                       GetSQLValueString($_POST['bomyear'], "text"),
                       GetSQLValueString($_POST['comments'], "text"),
                       GetSQLValueString($_POST['ID'], "int"));

Don't put anything in the value field.  Instead, you configure the MySQL column to be an auto-updating timestamp field.  

How do you touch the MySQL configuration?  Command line?  phpMyAdmin?

Hi JASON!  Wow you're the expert in all the fields that's great!  Hmm..Yeah I have phpmyAdmin.  I don't know how to set it to auto-update though from there.  I'm looking at the table structure and can't see anything regarding auto update in the table.

Okay, steps:

1. Log into phpmyadmin

(steps 2-4 refer to image 1)
2. Click on the table you want to modify on the left menu
3. If you are not taken to the Structure tab after step 2, click on it now.
4. Click the pencil icon in the column you want to modify

For steps 2-4
5. Set the values as I have it in image2 (substituting your name for the column, obviously)

Step 5
6. Change the Update Record behavior so you are not updating that column via form submission anymore.

That's it.

Jason, thank you so much for screenshots.  I took out the default and made the timestamp varilable in the table and now it works!  Genius and thanks again!
