Great I'm glad that it's working for you now.

I will keep your changes in mind. I've been meaning to update with a bit more functionality such as the bits you've included, but I've been too busy lately.

Thanks again

Before vBulletin.com ends support for vBulletin 3. Can you please be so kind as to update this mod and release this for vBulletin 4?

Yeah I plan to. In the mean time, someone else has posted some edits you can make to make this compatible with vb4

I heard somewhere on vbulletin.com native support for Google Checkout was coming soon for VB4. Might want to double check before you put in too much time.

I figured out the issue that some (or at least 1) person reported in this thread. There is a problematic intval() call in the form generation function. Merchant ID's are generally very large numbers. intval() is either a 32 bit or a 64 bit function, depending on the host. If it's a 32 bit system, it will max out and cap at the wrong value.

For those running into the "oops!" error, please fix the following line by removing intval:

$form['action'] = 'https://checkout.google.com/api/checkout/v2/checkoutForm/Merchant/' . intval($settings['gmerchantid']);

to this:

$form['action'] = 'https://checkout.google.com/api/checkout/v2/checkoutForm/Merchant/' . $settings['gmerchantid'];

They've been claiming they'll work on this since...forever....

I'll wait for a mod (think it will happen sooner -vs- bulletin.com)

if someone can be kind enough to let me use their vB4 forum, I can update this for vB4 in an hour tops.
