The code for the quicksort is essentially the one from
http://www.devx.com/vb2themax/Tip/18973.

For sorting  a single column, all I do is loop through the cells  loading
them into an array, pass that array to the quicksort routine, and then
write the sorted array back into the worksheet  using another loop -
admittedly, it's probably not the best way, but it works, is fairly
easy for others to understand, and has th eadvanyage of sorting both
text or numbers.

Does that help any?
