Clarification on eCart generation

Hi I had a few initial questions about usig eCart.

1. If I were to use the server behavior Insert Checkout Form it generates the code that has "eCart Local Checkout" on the checkout page (together with the "checkout with PayPal express button". I noticed that this page errors and located it on line 253:

<tr>

                <td><h3><?php echo(WA_getSavedFormValue('CheckoutWizard_NewFromBlank_Default','First_Name_2')?"Billing ":""); ?>Address</h3></td>

Why would it generate this code since its causing the error?

2. Also with regard to the Insert Checkout Form server behavior. Obviously it generates the code for local checkout and the Checkout with PayPal Express button...but the PayPal Express button is non functioning - what would be the appropriate direction to get this button functioning...since i would require the customer to enter the billing and shipping details from the form on this page (I want to store both billing and shipping details in the website database)...I ask this because using the main eCart Checkout wizard does a completely different approach.

3. Again with the Insert Checkout server behaviour...since it adds the server behaviour "eCart Local Checkout" on the checkout page...would I also place the "Create Email Message" and the "eCart Store Details" and "eCart Store Summary" on this page...or would I still need to place those on a confirm.php file that I need to create? Reason why I ask is that on the main eCart Checkout Wizard the "eCart Local Chceckout" is generated on the confirm.php page rather than the checkout.php page.

I have a few other questions, regarding the Preset Manager with eCart ( may have found a few bugs with with) but wanted to get the above clarified first :
