instead of using the count variable for the form element names in the repeat region:
<input type="hidden" id="Price_<?php echo($count); ?>" name="Price_<?php echo($count); ?>" value="<?php echo $row_WADAestimate['PricePerUnit']; ?>" />
use the ID column from recordset. For example:
<input type="hidden" id="Price_<?php echo $row_WADAestimate['ProductNo']; ?>" name="Price_<?php echo $row_WADAestimate['ProductNo']; ?>" value="<?php echo $row_WADAestimate['PricePerUnit']; ?>" />
In the template file, add the following code at line 1:
<?php global $row_WADAestimate; ?>
Then you can loop through the form elements using this code:
<?php do { ?>
<?php echo((isset($_POST["Price_".$row_WADAestimate['ProductNo'].""]))?$_POST[""Price_".$row_WADAestimate['ProductNo']."""]:"") ?>
<?php } while ($row_WADAestimate = mysql_fetch_assoc($WADAestimate)); ?>
