eCart 6.1.0 and Checkout Wizard

I hope these are not foolish questions to ask as I have attempted to find the answers through the webassist forums. And if there were a link I can be directed to that would be helpful. All address the current version of eCart, 6.1.0 on a Mac using OS 10.5.8 and adobe Dreamweaver CS4 (version 10.0 build 4117) testing through MAMP version 1.9.6.

After uninstalling Dreamweaver and removing the eCart extension and any files related to eCart and reinstalling Dreamweaver and downloading the eCart extension twice, the third time seemed to work and the error box did not show again. (ERROR, screen shot).

Created a products page, eCart Object and inserted the "add to cart" button several times as “add static item to cart” with no problem.

Using the eCart Display Manager I have supplied two screen shots for the settings I used (eCart Display Manager 1.png, eCart Display Manager 2.png).

Moving on to the eCart Checkout Wizard, I have supplied screen shots of the settings (eCart Checkout Wizard Settings, eCart Checkout Wizard Payments, eCart Checkout Wizard Shipping, and eCart Checkout Wizard Form Design) The screen shots of the first three show a slide bar under the heading on the left side which is inactive and may be a bug or a result of too many reinstalls of the extension.

I have included screen shots of the pages that were created Confirm Cart, Checkout Success, Cart and Checkout. The one, which seems unusual, is the Checkout. Not sure why the Billing information part of the form does not appear, the Shipping part on the right is cut off and the Order Confirmation at the bottom is not formatted.

I noticed that in addition to the cart.php page there are checkout_failure.php, checkout_success.php, checkout.php, confirm_cart.php, confirm.php, and pp_confirm.php pages generated. Are they all required?

Using the previous version of eCart 5.0.3 for another client and which I received help there were only checkout_failure.php, checkout_success.php, checkout.php, and confirm.php, pages generated. The PayPal link was via an email address with the fee that of the present PayPal Express.

Are the differences due to the PayPal Express selection, the present client does not want to pay monthly charges of a more elaborate account or a SSL certificate?

My last set of questions. Is it possible to have the word FREE appear in the handling section and shipping section of the form rather than $0.00 or no visual of both. And finally would you suggest reverting to the previous version of eCart 5.0.3 based on the operating system and software.

Thank you in advance and best wishes for the New Year.
