In a weird twist, I have/had  the script working, but again it is not 
working in FF or Chrome.  This is a link to the first page which runs you 
through the pages.

I have the submit to trigger upon change so there is no submit button.  This 
works in IE7.  If I add a submit button, it does not work in any of them.

I am wondering if this is more a problem with the html.


http://www.assessmentappeallawyer.com/forum_state.php

This is the code for the first processing page

if ( !isset($_POST['submit']) ) {
  echo '<form action="forum_delete.php" method="POST">';
  if ($Recordset1) {
    echo <<<HEADER
<table width=200 border=0>
  <tr><th> &nbsp; </th><th> State </th><th> County </th></tr>
HEADER;
    while ( $row = mysql_fetch_array($Recordset1) ) {
      echo <<<ROW
  <tr>
    <td><input type="checkbox" name="county[]" value="{$row['name']}"></td>
    <td>{$row['state_id']}</td>
    <td>{$row['name']}</td>
  </tr>
ROW;
  }//end while
  echo '</table>';
} else {
  echo '<p>Error performing query: '.mysql_error().'</p>';
}
  echo '<input type="submit" name="submit" value="Select" />';
}

?>

****This is the code for the second processing page.


<?php


if ( !empty($_POST['county']))
  foreach ( $_POST['county'] AS $id => $name )
    echo 'You have selected '. " {$name}".'<br />';



$totalRows_county_result_net= "($totalRows_county_result) + (1)";
 echo "[$totalRows_county_result_net]";
 echo "$totalRows_county_result";
 ?>
</div>
<!--eo center-->


<?php
$name=$_POST['name'];
echo 'You have selected'."$name";

?>
<?php
mysql_free_result($county_result);
?>

Again, thank you for any input.
