can you help me with this

You are to create a small website that allows users to view links related to their interests. Users must choose one topic from each list of items. When the user clicks the submit button, they're redirected to a page that displays a link for each selected item. If the user clicks on the link, they will visit the site. This project contains two separate ASPX pages.  One page displays the radio buttons, the other displays the links. 

Hi paul2811,

This requirement is not difficult, but its description is not clear enough for me. I write a simple demo for you. It may not exactly meet your request, but the logic is the same. I hope it is helpful to you.
