SOLVED - Paypal Error

I got this error at check out.

Unable to process payment. Please contact the merchant as the shipping address provided by the merchant is invalid, and the merchant has requested that your order must be shipped to that address.

maybe you need to configure your paypal plugin with your own merchant account. can you tell us more specific what the problem is?

Ok, now this has confused me even more.

What flag? I don't seem to have any flag in my module?

I'm sorry. I was adding the variable to the wrong paypal_end.php

It's working now. Thanks.

Hmmm... having the same problem, but the solution did nothing -- see "IS THIS THE RIGHT PLACE?" in my code below:

//<*php
			foreach( $vars as $name => $value ) {
				echo '<input type="hidden" name="'.$name.'" value="'.htmlspecialchars((string)$value).'" />';
			}
			$doc =& JFactory::getDocument();
			$doc->addScriptDeclaration("do_nothing( function() {document.getElementById('hikashop_paypal_form').submit();});");
			JRequest::setVar('noform',1);
			$vars["address_override"]='0'; // IS THIS THE RIGHT PLACE?
		//*>
	</form>
</div>

Unable to process payment. Please contact the merchant as the shipping address provided by the merchant is invalid, and the merchant has requested that your order must be shipped to that address.

That worked!
