Not found [CFN #0005] error

I have a DataAssist results page that submits form data to an eCart 'request for quote' page. I'm getting the error above, along with a blank page, on submit. Haven't found any info on web or in forums about this particular error. When testing on local server I get a different error:

'The requested URL /websitename.com/RequestforQuote.php1' was not found on this server.

Files attached with live link.

Your form action is set to:
action="RequestforQuote.php<?php echo $row_WADAProd['ID']; ?>"

I think your form action should probably be blank.

With no form action at all I get the following error:

from localhost:
Warning: Cannot modify header information - headers already sent by (output started at /Applications/MAMP/htdocs/websitename.com/Connections/ProductsDb.php:9) in /Applications/MAMP/htdocs/websitename.com/Prod_results.php on line 226

from Remote server:
The cart is empty

Files attached.

Also tried deleting only the php, but both local and remote servers showed: The cart is empty.

This implies that you have a blank line of code or error on line 9 of Connections/ProductsDb.php. Can I see a copy of that page?

The cart is empty because you have the quantity set to get the value from a form element named: eCart1_1_Quantity_Add and that form element isn't on the page. You could set that value to 1 in the add to cart interface and it should start adding the selected items to the cart.

This post has been deleted.

The quantity error was fixed using the 'eCart Get from Recordset' behavior and replacing the Quantity value with '1'.

Although this shows the items with a quantity in the cart, it also shows all the records without a quantity as well.

In addition, RequestforQuote.php doesn't show results from the select list. I get the following errors listed in PM.

It looks like you also have your weight column bound to a field: "eCart1_1_Weight_Add" which doesn't exist. You probably want to get that from your database instead.

The second error is as a result of this one.

If you want to get the quantity from the input field on the page, you would want to name it uniquely for each row so that it can be identified like:

name="quantity_<?php echo $row_ProdSizeSelectList['ID']?>"

and then you could bind it to that value by updating line 153 to:
$ATC_itemQuantity = "".$_POST["quantity_".$row_WADAProd['ID']] ."";// column binding

All I get now is a blank page at Prod_results.php. both at local and remote servers. The changes that have been made are:

Prod_results.php -
<input name=" textfield"> is changed to <input name="quantity_<?php echo $row_ProdSizeSelectList['ID']?>"
php at top of page has been changed to: $ATC_itemQuantity = "".$_POST["quantity_".$row_WADAProd['ID']] ."";// column binding
eCart Get from Recordset Server Behavior Quantity value is now: <?php echo $eCart1->DisplayInfo("Quantity"); ?>

Also, in eCart Get from Recordset Server Behavior, the weight has been changed to a Db value:
<?php echo $row_WADAProd['ContSize']; ?>

There is also a syntax error I can't get rid of at:

<?php
mysql_free_result($WADAProd);
mysql_free_result($ProdSizeSelectList);
?>

If you can give me FTP access I can debug what is going on.
