Still having trouble with eCart

While the previous problem with errors in sums has been corrected, we continue to have errors in getting this eCart working on our site. We have a link on this page: trans_av_hx2.html

In the upper right, a box says 'Invest in this project now' – when it is clicked, I linked it to our newly created PHP file with the eCart on it:

cart_trans_av_hx2.php

When clicked, it gives this error message:

Warning: require_once(WA_eCart/eCart_GGT_PHP.php) [function.require-once]: failed to open stream: No such file or directory in /home/content/s/t/e/stemtechlabs/html/globalgeniustrust.com/cart_trans_av_hx2.php on line 3

Fatal error: require_once() [function.require]: Failed opening required 'WA_eCart/eCart_GGT_PHP.php' (include_path='.:/usr/local/php5/lib/php') in /home/content/s/t/e/stemtechlabs/html/globalgeniustrust.com/cart_trans_av_hx2.php on line 3

WHY ISN"T THIS WORKING???

the error is saying that the eCart file cant be opened:
eCart_GGT_PHP.php

make sure that the WA_eCart/eCart_GGT_PHP.php file has been uploaded to the server.

Yes, it is uploaded to the server. Now I just get a blank page.

i cllicked on the link in post #1 and i got the add to cart page,

cart_trans_av_hx2.php

which added an item to the cart.

if you are still having problems, try adding the following lines of code to the top of your page...

<?php
error_reporting(E_ALL);
ini_set('display_errors','on');
?>

This is REALLY FRUSTRATION! To not get proper tech support for a product we purchased for a sustantial cost! Can you please call us and help us get this up and running, THis has gone on for almost three months now!

do you have another link that demonstrates the issue?

when i go to this page:
cart_trans_av_hx2.php

it displays correctly, with the add to cart button.

I press the add to cart button and the item is displayed in the cart.

Please see the attached screen shot.
