I resolved my earlier problem with the DB not updating when I changed the customers wholesale authorization level. For folks with similar problems, I just used the developers tool to search for instances of, "customer_whole", "customers_whole" and "customer_wholesale" and changed all to "customers_wholesale"

However, now I am able to identify a second problem. I have some products that are priced by attribute. The correct wholesale prices are displayed. However, when the item is placed in the shopping cart, the price reverts to the retail price. This only happens with products that are priced by attribute. I did download and install the revised attributes_controller.php (and reinstalled it this morning just in case).

This time, I don't think I have missed a variable change. Any other suggestions where to look for this one?
