Re: numeric SORT order

thanks Mitch.
the problem is that casting to int won't work for non-numeric data
(obviously), and I can't guarantee that values in this column will
definitely be numeric... I should have made that clearer in my post. Ideally
I'd like to sort numbers in numeric order and text in regular alphabetic
order, like: 1,2,3,40,50,a,b,c,d,e...[etc]
