Selecting appropriate radio button and displaying it in the next page RRS feed

  • Question

  • User441592953 posted

    Hello everyone!

    I am trying to accept a random row from a table and inserting the values of different columns properly in the appropriate radio button.

    Upto this its working fine.

    Now I want to check which radio button was selected. Just out of curiosity, I took a session variable and tried to store the selected radiobutton value in it and display it on the next page on the click of a button. But I am getting wrong result for the different click of the submit button.

    Please help.
