How-to Google Upload of Store Products

I would like to thank Litriem for the guide on how to set up the feed, it saved me a lot of head scratching.

Little help, followed the instructions to the letter. I'm running 1.4.9.2. Ran it three times just to be sure. It doesn't appear google can even retrieve the data.

I am getting this error on google:

Get file entry failed. (1 error)

Failed to obtain the file information. Please make sure it's available.
Examples:
Url
http://www.griffinbrook.com/opencart/in ... oogle_base

Google came back to me and basically said the same thing.

Thank you for your email.
I have reviewed your account and noticed that The URL you have used for
scheduled data feed upload

unreachable. Please ensure that this URL points to your data feed file
directly and not to any other page.

Ideas?

I got mine to SEMI-work on 1.5.1.3 ...sort of. Here is what my code looks like

$output .= '<g:quantity>' . $product['quantity'] . '</g:quantity>';
//$output .= '<g:upc>' . $product['upc'] . '</g:upc>';
$output .= '<g:weight>' . $this->weight->format($product['weight'], $product['weight_class_id']) . '</g:weight>';
$output .= '</item>';

BUT It only shows 6 products. How can i show them all??? Any help
