quick questions - checkout page edit

i am using zencart 1.3.8a

-- I would like to add a text right above the submit button in the checkout process, but i am not sure which file i need to edit to add that text?

Depends on what page.

The first would be tpl_checkout_shipping_default.php, then tpl_checkout_payment_default.php, etc.

The file names in Zencart (with a few exceptions) pretty clearly describe the file's function, and most pages are styled/controlled by a file that begins with tpl_.

Steve, do you know how to change the order of the form field as they appear on the checkout page?

Which checkout page?

The checkout page of the Zen Cart.

Let's start over. There are at least 3 checkout pages in a regular Zencart process: shipping, payment and confirmation.

What exactly do you want to add/remove/change and where?

I mean the page where the customer enters their credit card details.

I've been asked to change the order of the form fields in checkout page on my firms Zen Cart. They want the credit card start date field to be shown before the credit card expiry date and the CVV number to appear after the credit card expiry date.
