XML formatting error

Hey

I have been trying to add my product feed to Google Merchant, this is the error i get:

“The product data you submitted in your feed does not meet the product data specification, so your products were not approved. Fix and update your feed to display products to customers. To see all issues, go to Diagnostics.”

“XML formatting error”

I have contacted google to attempt to get a more specific reason for the error. They are unable to provide any further informtion and suggest its a Plugin/Feed issue and I should contact the plugin producers for help.

This is the first time I have ever created a feed, so please forgive me If I have missed something, but it looks fine to me.

Any suggestions?

Regards
Nobby
