i have two tables. i have to select a class name from first select box and then a query must fired which will check how many sections for that class exists in the table, for ex. if for class "1" we have section "a" and "b" then in the next selection box only 2 options as "a" and "b" must appear, if there are 3 section then "a","b","c" must appear.
