I have an .asp page displaying a recordset say col1,col2,col3,col4 from a table.Also there are 4 radio buttons col1,col2,col3,col4
On click of any of the radio buttons I would like the rs to be sorted by the corresponding column

say if the clicks on the col4 radio button, the page needs to be refreshed with the rs based on
"select * from tab1 order by col4"

I know this must be simple. Could anyone help?
Thanks
