OK here is where I am now. I appreciate all of the help.
But still no dates are passed in the url....its blank, like this.
The links look like this..../index.php?date=
Heres my code
<?php
$date = isset($_GET['date']) ? $_GET['date'] : date('Y-m-d');
$previous_date = date('Y-m-d', strtotime($date .' -1 day'));
$next_date = date('Y-m-d', strtotime($date .' +1 day'));
?>
<a href="index.php?<?php echo date?>=<?php echo $row->$previous_date;?>" > Previous </a>;?> Todays Date <a href="index.php?<?php echo date?>=<?php echo $row->$next_date;?>" > Next </a>;?>
