data feed?

I need the feed URL for the googlebase.xml ....can anyone tell me how to get this?

admin - Extensions - Product Feeds

after installing it, edit the Google Base feed, enable it and grab the URL it gives you

thanks ... we did that, but it was disapproved because one of our products has a # in the product assignment. see below-- I have tried everything to get rid of it, I deleted the product but it still shows up on the xml. spreadsheet.

any advise??
thanks!

-<assignment><opencart_field>Product</opencart_field><opencart_field_value>BENSEN Canyon Daybed- CANDBD</opencart_field_value><google_attribute>google_product_category</google_attribute><google_attribute
_value># Google_Product_Taxonomy_Version: 2011-10-21</google_attribute_value></assignment>

I've no idea what those tags are, they certainly dont come from the default Google Base feed.

Have you installed something else ?
