Hi, I am new to this concept,
In a page there are 5 select boxes and 2 radio buttons.
First select box has standard ID , second select box has respective section id, after selecting rest of the three selectboxes final I have to select either first or second, if I select Second radio button,I have to get the selected Standard Id and Section ID, by that I have to download the all the values in excel from mysql database based on standard and section id. I did not submit it,

While clicking the second radio button only it all has to happen. How to do?

What you have done so far, submit it here?
