Cart Upsell/CrossSell on Shopping-Cart Page

I instealled this module and now am getting the following error on my shopping cart page.

1044 Access denied for user: 'myUserName@%' to database 'myDBName'
in:
[create temporary table cross_sell ( products_id int(11), products_image varchar(64) )]

I've double checked that my database connections are correct and don't see db errors for any other pages. Any help is greatly appreciated!

Is anyone able to shed some light on this problem, I have installed the cross sell mod and it is working fine however when I try to get the cart upload mod working I receive an almost identical error.

The only thing I think it could possibly be is where the script is getting the database user name etc. from.

My error says localhost but I Zen-Cart configured to run from an IP address.

Any ideas?

i istall this contribution but onlt get an error message...(V1.3.7)
