Sort Order incorrect
I'm attempting to sort columns using the Sorting by Column Link recipe solution. I am trying to sort 3 columns; by id, lastName, registered (date).
The id and registered appear to be sorting correctly. however the last name column is not sorting correctly; it's not alphabetical.
This is a results page and I am using pagination; showing 15 records at a time.
Can you tell me if I'm doing something incorrect?
Thank you in advance
