I'm sorry but I don't understand this. I wasn't sure in the first place why you couldn't use the ASC abreviation but the line I gave you does not need any changes to the Users table. The only change I have made as far as I am aware is the display of the option on the page. But if you've managed to fix your problem that's fine.
You are right -- I didn't need to change the Users table. Maybe I'm not thinking 100% straight because I'm in too much of a hurry to fix this.
