I made the changes as suggested and the result created errors on the page without fixing the problem. So I replaced the checkout.php with a fresh copy and opened it with dreamweaver and made some modifications. Like I said before "I am a complete newbie, I am not a code writer". I used split veiw and individually hi-lighted and deleted everything I did not want, like credit card information, etc. So that all that was left on the page was the PayPal Express checkout button. Tried it out and the page worked.
Next I opened the PP_cancel.php file and on line 277 I changed "checkout.php" to "cart.php" and the word "checkout" to "cart"
Then I opened the PP_checkout_failure.php and on line 278 I changed "checkout.php" to "cart.php" and the word "checkout" to "cart"
I repeated the above on line 279 of the checkout_failure.php file
Now I do not have to worry about a customer being asked to enter their information erroneously to checkout. Now when the customer is directed to either a checkout failure, PP checkout failure, or PP checkout cancel they will be directed back to the cart so they can either try to checkout again through PayPal Express or clear their cart.
for those who wish to check out what I have done, my site is:
there is a product under the catagory of "tools" called "test-not real product" priced at $0.01
I hope this information is of help to others with the same problem
Now to see if I can figure out my problem I have in the thread "checkout problem"
